ABSTRACT:
To present a liquid crystal device high in contrast, bright and possessing high speed response characteristics, and to present electronic appliances such as liquid crystal display device and image pickup apparatus of high contrast and brightness, copier, printing plate process machine, facsimile communication apparatus, optical communication apparatus and image operation apparatus. A liquid crystal device comprising a pair of substrates forming electrodes respectively on the confronting surfaces, a power supply for applying voltage to the electrodes, and first and second liquid crystal layers interspaced between the pair of substrates, in which the first and second liquid crystal layers are contained in a three-dimensional reticular high molecular weight compound, the directions of orientation of liquid crystal molecules are aligned almost in one direction, and the directions of their orientations are mutually different near the substrates.
