Abstract

PURPOSE: To make thin the device and to improve the deterioration, by using only one polarized plate for the liquid crystal display unit, through the use of reflection plate having higher reflection rate to the polarization of a given direction in the reflection plate surface.
CONSTITUTION: In place of one plate of two polarized plates used for conventional liquid crystal display panel, the reflection plate 20, for example made of (SN) X singlecrystal, is provided. The plate 20 as higher reflection rate to the polarized light toward a given direction and has the charcteristics changed with the wave length. With this consisution, when the voltage between the transparent electrodes 17A and 17B is zero, the reflected light of the plate 20 exerts externally while changing the direction of polarization as shown in 22. Further, a voltage higher than the threshold voltage is fed to the electrode, the direction of polarization is as shown in 25, and it is absorbed with the plate 20 and no light is introduced externally. Accordingly, the display can be made. That is, this display panel is thin and has less effect due to the deterioration of the polarized plate. Further, when the reflection plate in which the reflection rate is dependent on the wave length, is used, the color display can be possible.
