Abstract: A donor sheet for transferring an image pattern to an image receiving element by a thermal imaging process using laser beam, comprising a base having formed in order on the base a light-to-heat conversion layer, and a transfer layer containing an image component which is melted by heating due to an action of the light-to-heat conversion layer and transferred to the image receiving element in a patterned form, in which the image component of the transfer layer contains an ink-repellent or solvent-repellent compound in an optimized amount. Using the donor sheet, it becomes possible to produce an separation member such as partition pattern and black matrix of a color filter by a shortened manufacturing step with ease and accuracy at high contrast, and can impart excellent ink repellency to the separation member.

Abstract: Disclosed is a method of producing a transmissive screen having a structure including light-absorption-material patterns (102) that are formed on locations corresponding to locations of lens members (105), which are provided side by side on a light-transmissive substrate (101), and to locations of boundary portions between the corresponding lens members (105), the method comprising the step of forming at least one of volume-type phase devices (802) and precursors of volume-type phase devices (802) by causing drops of volume-type phase device compositions to be discharged and to land, with the volume-type phase devices (802) having random phase distributions being provided side by side on at least one of a surface of the light-transmissive substrate (101) where the lens members (105) are formed and the back side of the surface. It is possible to provide a method of producing a transmissive screen, which makes it possible to realize at a low cost a bright transmissive screen which has high contrast ratio and which can display a high-quality image having no moiré and no speckles.

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 self-assembled monolayer (SAM) is fabricated using either a semi-fluorinated sulphur containing compound or a semi-fluorinated silane derivative and compressed carbon dioxide (CO 2 ) as the solvent medium. The temperature and/or pressure of the compressed CO 2 may be varied during the fabrication process to improve the molecular packing density of the monolayer. A co-solvent may be used in conjunction with the compressed CO 2 . The substrate may be a metallic substance. Also claimed are inkjet heads, electronic, optical or optoelectronic devices, e.g. a thin film transistor, an organic semiconductor device, or a light emitting diode, comprising a self-assembled monolayer constructed by the process.
