Abstract
A liquid crystal display includes a liquid crystal layer causing a selective reflection and exhibiting Kerr effect, first and second electrodes applying voltage to the liquid crystal layer, a first circular polarizer disposed between the liquid crystal layer and a viewer and allowing a first circularly polarized light incident on the liquid crystal layer when irradiated with a natural light, the first circularly polarized light having an electric-field vector rotating in a direction reverse to a rotation direction of an electric-field vector of a circularly polarized light selectively reflected by the liquid crystal layer, and a second circular polarizer facing the first circular polarizer with the liquid crystal layer interposed therebetween and allowing a second circularly polarized light incident on the liquid crystal layer when irradiated with a natural light.
