Abstract
PURPOSE: To establish the display not requiring lamps at night and not considering the effect by radiant rays, by forming the reflection plate with phosphorus substance, in liquid crystal panel of reflection type.
CONSTITUTION: In the twist nematic type display unit having the glass plate 2 having the transparent electrode, spacer 4, and liquid crystal 5, between the polarized plates 1 located orthogonally each other, the reflection plate 30 consisting of phosphorus substance is located at the back. Since the phosphorus material is different from fluorescent substance, in the luminescence in which absorbed energy is radiated as light, emits light with sufficiently longer attenuation time. The device is stimulated with external light at daytime, by mixing the phosphorus substance in the reflection plate or forming the reflection plate by the substance, and the plate plays a role of illumination plate at night, and the content of display is uniformly illuminated.
