Abstract
A TN liquid crystal is used as a liquid crystal panel, and a polarizer is provided above the TN liquid crystal while a polarizer , a light scattering layer and a polarized light splitter are provided in this order under the TN liquid crystal . Furthermore, under the polarized light splitter , there is provided a light guide for introducing light of a light source from under the polarized light splitter and a reflecting plate . The polarized light splitter is a reflecting polarizer which can accomplish the effective utilization of light so that extremely bright reflective and transmissive displays are obtainable. Additionally, since a light diffusing layer is provided, even if the distance from the TN liquid crystal to the reflecting plate is prolonged, in the reflective display, no double image nor display bleeding occurs.
