Abstract: PURPOSE:To enable the detection of recorded signals with a high sensitivity regardless of the bearings where a photochemical hole burning wavelength multiple recording medium is placed by irradiating this recording medium with circularly polarized light and detecting the deviation of the transmitted light or reflected light. CONSTITUTION:The light radiated from a wavelength variable laser 7 is polarized to the circularly polarized light by a polarizer 1 and a quarter-wave plate 2. A sample 3 in a cooler 4 is irradiated with this light. The circularly polarized light enters a quarter-wave plate 5 while its circularly polarized state is held maintained if the sample 3 as the recording medium has no dichromaticity. The light transmits this plate in the form of linearly polarized light. The light does not pass the plate if the polarizer 6 is disposed perpendicularly to the polarization direction thereof. The circularly polarized light is, however, disturbed and is polarized to elliptically polarized light elongating in the polarization direction where the absorption is weak if the sample 3 has the dichromaticity. Such phenomenon can be considered by dividing the light to the component of the circularly polarized light and the component of the linearly polarized light. The linearly polarized light component does not depend on the polarization direction and passes the quarter-wave plate 6 and the polarizer 6 at a specified ratio. This light is detected by a photodetector 8.

CONSTITUTION:A cyanine dye having absorption max. within a 660-690nm wavelength region in a methanol solution is dissolved in a proper org. solvent to be applied to a substrate 1 composed of plastic such as polycarbonate or acrylic resin and dried to form an org. dye layer 2 absorbing laser beam to perform photothermal conversion. A metal such as Au, Cu or Al is applied to said org. dye layer 2 by vacuum vapor deposition to laminate a metal reflecting layer 3 and, if necessary, a protective film 4 composed of an ultraviolet corable resin is further provided to form an optical data recording medium. The aforementioned cyanic dye is one wherein heterocyclic rings are bonded by a methine chain.

Abstract: PURPOSE:To ensure excellent handleability, resolution and long-time stability, eliminate the need for peripheral apparatuses for application of an electric field or reading and enable application to gradational recording and copying, by using as a main constituent a high molecular weight nematic liquid crystal having an isotropic phase transition temperature higher than the glass transition temperature thereof. CONSTITUTION:A photothermal recording layer 3 comprising a high molecular weight nematic liquid crystal having an isotropic phase transition temperature higher than the glass transition temperature thereof as a main constituent is provided on a substrate 1. The liquid crystal is characterized by a clearing point in a temperature region higher than the glass transition point. The clearing point is defined as a temperature at which the intensity of transmitted light is rapidly lowered to zero through transition to an isotropic phase after the intensity reaches a peak with a conspicuous increase in optical anisotropy due to formation of a liquid crystal phase as temperature is raised, in observation under a cross polarizer. The liquid crystal preferably has a molecular weight of 10000-200000, and is optimally a side chain type high molecular weight liquid crystal, for example, those based on a chanophenyl benzoatemethoxybiphenyl benzoate copolymer, cyanobiphenyl, or phenyl benzoate azomethine.

Abstract: PROBLEM TO BE SOLVED: To prevent burning of a pixel due to a decrease defect.
SOLUTION: A write transistor 210 writes a video signal from a data line 110 into a holding capacitor 230 according to a control signal from a scanning line 120. A drive transistor 220 supplies such a drive current to light emitting elements 240 and 340 according to the voltage written into a holding capacitor 230. The light emitting elements 240 and 340 emit light according to the magnitude of the drive current. When the light emitting element 340 turns to a decrease defect, the current supplied to the light emitting element 349 becomes excessive, and low fusing wiring 361 is fused by the excessive current. At this time, the driving current equal to the summation of the current supplied to the two light emitting elements which normally emit light is supplied to the light emitting element 240.

Abstract: PROBLEM TO BE SOLVED: To provide a light emitting element which improves image quality by reducing reflection of external light or an outside view.
SOLUTION: This light emitting element has a resonator structure for resonating light emitted from a light-emitting layer 13B between a first end P1 and a second end P2 and extracting it from the side of the second end P2. The light emitting element is structured such that the intensities and phases of reflected lights h1, h2 of the external light on the side of the first end P1 and on the side of the second end P2 are adjusted so that a reflection coefficient of the external light H at a resonance frequency incident from the second end P2 side is set not greater than 20%, and more specifically, adjusted so that the intensities are set almost identical to each other and the phases are reversed from each other. The intensities of the reflected lights h1, h2 are adjusted by materials and thicknesses of a first electrode 12 and a second electrode 14. The phases of the reflected lights h1, h2 are adjusted by an optical distance L between the first end P1 and the second end P2.

Abstract: PROBLEM TO BE SOLVED: To provide an inspection device capable of performing the inspection work of a plurality of devices to be inspected as quickly as possible. SOLUTION: An inspection machine 21 inspects a plurality of organic EL displays D while being rotated around a rotation axis J1 in a state where the plurality of organic EL displays D are held on the curved surface of a maintenance wall 10 having a semi-cylindrical curved structure. Since the inspection device is different from a conventional inspection device for inspecting the plurality of organic EL displays while the inspection machine is linearly moved in two directions by using an XY stage, and the inspection machine 21 needs not be moved at the time of the inspection work, the time for the movement of the inspection machine 21 is not required. Therefore, the time required for inspection work by the movement time of the inspection machine 21 is reduced, and the time required for the inspection work of the plurality of organic EL displays D is reduced.
