Abstract
A transflective liquid crystal display that includes a liquid crystal layer interposed between a pair of substrates facing each other and a transparent display area for transparent display and a reflecting display area for reflecting display within a single pixel area, wherein the liquid crystal layer is composed of a quasi-isotropic liquid crystal material that is optically isotropic when non-selected electric field is applied and is optically anisotropic when selected electric field is applied, the flexibility of which changing according to the electric field intensity, and the electric field intensity is supposed to be set smaller in the reflecting display area than in the transparent display area.
