摘要： A homeotropic-alignment liquid crystal display device having a high photostability and a high contrast ratio and a method of producing the same are disclosed, wherein while two glass substrates having patterned transparent electrodes are set obliquely at a first angle with respect to an evaporation source, then a first SiO.sub.2 film is deposited on each of the glass substrates while irradiating the glass substrates with an ion beam emitted from an ion gun. Subsequently, the glass substrates are turned in their planes over an angle of 90 degrees and set obliquely at a second angle with respect to the evaporation source, and thereafter, a second SiO.sub.2 film is deposited on the respective first SiO.sub.2 films while irradiating the first SiO.sub.2 film with the ion beam. The first and second SiO.sub.2 films thus deposited on the glass substrates jointly form homeotropic-alignment undercoat films. A homeotropic alignment film is applied to each of the undercoat films, and after that the glass substrates are assembled together via spacers and filled with a liquid crystal.

摘要： An alignment layer to be used for liquid crystal displays each having at least two substrates with liquid crystals sealed therebetween is formed as follows. The substrates placed on each of several substrate trays are heated in a first load-lock chamber. At least one of the two substrates is irradiated with evaporated particles of oxide silicon (SiOx: 1.0≦×≦2.0) by vacuum deposition at an angle in the range from 45° to 60° from a direction of the normal line on the substrate surface to form an alignment layer thereon while the substrate trays are being moved in a layer-deposition chamber intermittently or sequentially. The substrate trays are cooled in a second load-lock chamber, thus producing substrates each formed the alignment layer thereon. The deposition chamber may be set under a requirement 0≦&Dgr;&thgr;≦3° in &Dgr;&thgr;=tan−1)dcos &thgr;/(D+d sin &thgr;)), “d” a distance from the substrate center to the center of a substrate edge, “D” a distance from the substrate center to the center of an evaporation source containing the oxide silicon, and &thgr; an angle formed between a direction in which the normal line extends on the substrate center and another direction in which evaporated particles of oxide silicon are deposited on the substrate center from the evaporation source.

摘要： A spatial light modulation device of the type, in which information is written to a photoconductor by a light writing portion and read light impinging on a light modulator is reflected by a reflection portion. This spatial light modulation device is provided with a dielectric mirror mounted on a reflection surface of the photoconductor, which surface is opposed to the other surface on which write light is incident. The reflection surface of the photoconductor reflects lights having wavelengths near a wavelength at which the photoconductor has a maximum sensitivity. Thereby, the spatial light modulation device can have a high sensitivity.

摘要： A dielectric mirror of a spatial light modulator having a photoconductive layer on which an image is written by a writing light carrying an image information and a photomodulator layer through which the written image is read out by irradiating a reading light and by reflecting the reading light with the dielectric mirror. The dielectric mirror is constructed by laminating plural kinds of layers respectively having different values of refractive indexes, for instance, Si layers and SiO.sub.2 layers. The resolution of the spatial light modulator degrades when an oxygen content rate in the Si layers becomes below a certain amount, on the contrary, the contrast ratio of the spatial light modulator degrades when the oxygen content rate in the Si layers becomes above a certain amount. The Si layers of the present invention have an oxygen content rate ranging from 10 to 40 atom %, preferably ranging from 15 to 35 atom %.
