Abstract: An information recording method for recording desired information, wherein a control circuit (150) identifies a characteristic of light corresponding to information to be recorded, in accordance with table data stored in a table memory (151), indicating a corresponding relationship between the information to be recorded and the wavelength of the light and selects a light emitting material which emits the identified characteristic of the light in response to energy (electricity or light) supplied thereto, and a recording head (110) forms a light emitting element by supplying the light emitting material on a substrate (10) of a recording medium. Furthermore, energy is supplied to the recording medium on which the information is written so that the light emitting material emits light, the characteristic of the light is identified and the information is reproduced in accordance with the identified characteristic. The security of the information is enhanced with a new and easy method of information recording.

Abstract: A projection display apparatus employing organic EL elements is presented that is light in weight, is small in size, and can be practically implemented. In particular, the apparatus suppresses light-emission performance degradation caused by generated heat, thereby extending useful life, stabilizing brightness, and securing continual maximum brightness. The apparatus comprises: liquid crystal panels 12R, 12G, and 12B; light emitting units 13R, 13G, and 13B, positioned at the back of the liquid crystal panels and provided with organic EL elements as light emitting layers; and cooling bodies 14R, 14G, and 14B, positioned at the back of the light emitting units, for dispersing the heat generated by the light emitting layers. The cooling bodies 14R, 14G, and 14B may, for example, be electronic cooling elements that employ the Peltier effect to absorb and radiate the generated heat. Alternatively, the cooling bodies may be configured as heat-dispersing fins that guide and disperse generated heat.

Abstract: A thin film device fabrication method in which a thin film device formed on a substrate are transferred to a primary destination-of-transfer part and then the thin film device is transferred to a secondary destination-of-transfer part. A first separation layer (120) made of such a material as amorphous silicon is provided on a substrate (100) which allows passage of laser. A thin film device (140) such as TFTs are formed on the substrate (100). Further, a second separation layer (160) such as a hot-melt adhesive layer is formed on the thin film devices(140), and a primary destination-of-transfer part (180) is mounted thereon. The bonding strength of the first separation layer is weakened by irradiation with light, and the substrate (100) is removed. Thus, the thin film device (140) is transferred to the primary destination-of-transfer part. Then, a secondary destination-of-transfer part (200) is attached onto the bottom of an exposed part of the thin film device (140) via an adhesive layer (190). Thereafter, the bonding strength of the second separation layer is weakened by such means as thermal fusion, and the primary destination-of-transfer part is removed. In this manner, the thin film device (140) can be transferred to the secondary destination-of-transfer part (200) while maintaining layering relationship with respect to the substrate (100).

Abstract: A liquid-crystal projection device according to the present invention comprises an organic electroluminescent element 12 that is constituted by sandwiching an organic thin-film layer (125) between an electrode layer (126) that reflects light and a transparent electrode layer (123) that transmits light, and a transparent liquid crystal panel (20) that controls passage of light emitted from the surface of the organic electroluminescent element 12; and also comprises a half-mirror layer (121) arranged on the side where light is output from this transparent electrode layer (123) and that reflects some of the incoming light through the transparent electrode layer (123) to electrode layer (126) and that transmits the rest of this light; the distance between the half-mirror layer (121) and the electrode layer (126) being set to the optical distance of resonance of this light.

Abstract: Provided is a molecule comprising a structural component (A) which decomposes when irradiated with UV light having a wavelength in the range 254-400 nm (such as an o-nitrobentyl ester), and a structural component (B) which is hydrophobic and/or lipophobic (such as a fluorinated chain). Such a molecule may form all or part of a self-assembled monolayer film on a substrate. Also provided is a monomolecular film coated substrate (10), the film being formed from molecules comprising a structural component (B) which is hydrophobic and/or lipophobic, and a structural component (A) which decomposes (step (2) to (3) in figure 2) when irradiated with UV light having a wavelength in the range 254-400 nm to cleave away a part of the molecule comprising the structural component (B) leaving a residual hydrophilic structural component (C). Such a substrate can be photopatterned by image-wise irradiating it with UV light having a wavelength in the range 254-400 nm through a patterned mask to cleave the coated molecules at the structural component (A) thus removing the structural component (B) from the coated film in the irradiated areas converting them from being hydrophobic and/or lipophobic to hydrophilic. Where the substrate has a hydrophilic surface, the monomolecular film may be formed entirely from the UV decomposable molecules. Otherwise, the film may be that of a coupling compound which comprises a hydrophilic moiety and the latter is subsequently reacted with the UV decomposable molecules (step (1) to (2) in figure 2).

Abstract: An efficient multiple-wavelength light emitting device is provided. This multiple-wavelength light emitting device comprises a light emitting layer 4 for emitting light containing wavelength components to be output, a negative electrode 5 that is positioned at the back surface of the light emitting layer and that transmits at least a portion of the light, reflecting layers 7R, 7G, and 7B, positioned at the back surface of the negative electrode, for reflecting, of the light emitted through the negative electrode to the back surface, light having specific wavelengths, which reflecting layers are stacked up in order perpendicularly to the light axis, in correspondence with the wavelengths of the light to be reflected, thus configuring a reflecting layer group 7. In the direction perpendicular to the light axis, divisions are made in any of at least two or more light emission regions which reflect light of different wavelengths. In each light emission region, the distance between the reflecting surface of the reflecting layer 7 on the semi-transparent side and the reflecting surface in the semi-reflecting layer 2 is adjusted in this configuration so that it becomes a resonating optical path length for the light that is emitted in the light emission region.
