    摘要： A reflective liquid crystal display device has a liquid crystal cell formed by laminating upper and lower orientation layers 11 and 21, upper and lower electrodes 14 and 24, upper and lower substrates 12 and 22, and upper and lower polarizers 13 and 23 arranged in order above and below a liquid crystal layer 10 so that they may face their counterparts respectively. The liquid crystal cell is provided with viewing angle dependence so that the light transmission ratio of the dark display section to the bright display section for the light incident at the required angle may be less than 2 at the required azimuth angle of the liquid crystal cell, and the direction of the required azimuth angle is aligned with the direction of the main light source incident into the liquid crystal cell.

    摘要： An illumination apparatus provides an improved light utilization efficiency and improved collimation. The illumination apparatus has a light guide, a collimating unit provided at least on one side of the light guide for collimating rays incident on the light guide, and a light source disposed in the vicinity of the collimating unit and surrounded by a reflector. Preferably, in order for the light guide to be able to emit collimated light uniformly from its emission surface, the light guide has inclined reflecting irregularities or stepwise reflecting plates which are provided directly or via an air gap on a back surface opposite to the emission surface thereof, wherein the inclined reflecting plates are specular-finished at least on the inclined portions.
