    摘要: A projection apparatus includes three liquid crystal panels for independently controlling respective color light components of red, green and blue for a color image to be reproduced. The apparatus further includes devices for subjecting the respective color light components to additive mixture so as to reproduce the color image. Each of the liquid crystal panels is constituted by a nematic type simple matrix liquid crystal panel having twist angle .phi. of its liquid crystal molecule represented by210.degree..ltoreq..phi..ltoreq.300.degree..

    摘要: A multi-layered liquid crystal display device is disclosed, which includes a stack of liquid crystal layers in which the longitudinal axes of the liquid crystal molecules extend spirally, the liquid crystal layers being disposed in parallel with the spiral axes. A voltage supply is provided for supplying a voltage to at least a portion of the liquid crystal layers for conversion of the molecular alignment. Also provided is a pair of polarizers for making visible the conversion of the molecular alignment. More particularly, the polarization direction of the polarizers or direction normal to the polarization direction is deflected within the range of 3.degree. to 15.degree. with respect to the longitudinal direction of the liquid crystal molecules in a sense to reduce the spiral angle of the liquid crystal layers and the deflection angle is substantially in alignment with the longitudinal direction of the liquid crystal molecules.

    摘要: A lighting apparatus including a tubular light source and a member having a plurality of reflective surfaces which are angularly set such that light from the light source is reflected in a predetermined direction of a viewing angle by each of the reflective surfaces. A ratio of an apparent width of each of the reflective surfaces to an apparent interval of adjacent ones of the reflective surfaces, when viewed from the predetermined direction of the viewing angle, is so set as to be a function of a distance between the light source and each of the reflective surfaces.

    摘要: A liquid-crystal composition to be used in a multiplex-driving system in a twisted nematic (TN) type liquid-crystal display devices of the present invention is extremely superior in its display characteristics, and is able to meet sufficiently the demands to increase the information content of various liquid-crystal display devices of high-level multiplexing operation. The liquid-crystal composition is more considerable in its usefulness than the validity thereof in half-tone display especially when it is used in a liquid-crystal television.
