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： A display device, which is adapted for time-division driving and is free from occurrence of crosstalk, includes a pair of substrates which are arranged to be opposite to each other and at least one of which is transparent, electrodes provided respectively on surfaces of the substrates facing each other, and a material which is sandwiched between the electrodes and the light transmitting quantity of which is changed by an electric field applied between the electrodes. The electrodes formed on the surfaces of the substrates facing each other constitute scanning electrodes and signal electrodes which intersect each other to form display portions. The signal electrodes constitutes independent electrodes formed independently of each other in units of display portions. Outside leads of the respective independent electrodes are passed through the substrate provided with the electrodes and are led out to the back surface of the substrate.

摘要： In a liquid crystal display device, light transmitting through a liquid crystal layer is colored depending on the structural conditions of the liquid crystal display device. The phase of the transmission light is corrected by means of a phase correction plate to make the transmission light approximate achromatic color, thereby permitting monochromatic display or color display.
