摘要： Red incident light is reflected on a mirror (19) and linearly polarized by a polarizer (26R). Linearly polarized incident light enters a transmissive liquid crystal device (11R), in which oblique incident light is changed into elliptically polarized light. A retardation compensator (27R) between the liquid crystal device (11R) and an analyzer (28R) has an inorganic form birefringence layer. The retardation compensator (27R) yields birefringence effect to change elliptical polarized light into linearly polarized light. Linearly polarized light from the retardation compensator (27R) can pass the analyzer (28R) without decreasing intensity, and enters a color recombining prism (24). The liquid crystal device (11R) may have the inorganic form birefringence layer. Retardation in green and blue light is also compensated in the same manner. Red, green and blue image light, mixed in the color recombining prism (24), is projected onto a screen 3 by a projection lens system (25).

摘要： A transparent base plate supports a first compensating layer, which is adapted to compensate for a phase difference due to liquid crystal molecules having undergone normal orientation in a liquid crystal layer of a TN liquid crystal display device, and second compensating layers, which are adapted to compensate for the phase difference due to the liquid crystal molecules having undergone hybrid orientation in the liquid crystal layer. Each of the second compensating layers is constituted of one of oblique incidence vacuum deposited films, which are formed on opposite surfaces of the base plate with oblique incidence vacuum evaporation of an inorganic material. An azimuthal angle and/or a polar angle of a direction of vacuum evaporation with respect to a plane of vacuum evaporation is set to be different between the second compensating layers.

摘要： An image-forming apparatus for exposing a photosensitive material with image light. An optical modulation device is provided such that the intensity of image light made incident from one side of an optical modulator is modulated in correspondence with the intensity of the image light made incident from the other side of the optical modulator as well as a drive voltage to be applied, and the image light made incident from one side is made emergent from the optical modulator. Since the modulation of the intensity of the image light is effected by the optical modulator, the amount of exposure supplied to a printing paper is controlled in correspondence with the density distribution of the image on a negative film, and an image having appropriate contrast can be reproduced by effective use of the latitude of the printing paper.
