Abstract
A liquid crystal device including a liquid crystal layer comprising a liquid crystal of a dispersed type in which liquid crystal molecules are randomly distributed so that an incident light impinging against the liquid crystal molecules scatters to produce a white display spot. A polarizer and an analyzer are arranged on either side of the first and second transparent plates. A directional backlight is arranged on the outside of the polarizer for supplying light having a directivity in the direction perpendicular to the first and second transparent plates toward the polarizer.
