ABSTRACT:
A liquid crystal display device includes a light-responsive fluorescent screen that luminenesces at least one kind of visible light when activated by a U.V. light impinging on the screen. The device further includes a liquid crystal cell disposed in front of the luminous surface of the fluorescent screen and an irradiating device for impinging the active light onto the fluorescent screen so as to enable the display device to display a two dimensional image at a high speed with a high quality even though it uses a simple matrix address driving system for the liquid crystal cell. The display device incorporates an intercepting layer composed of glass plate or plastic film which intercepts black light discharged from the fluorescent screen to prevent the leakage of harmful U.V. rays to the outside of the display device.
