本発明は、フラット・ディスプレイ・パネルに関し、特
に多目的情報表示用液晶フラットφディスプレイΦパネ
ルに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a flat display panel, and more particularly to a liquid crystal flat φ display Φ panel for displaying multipurpose information.
従来、この独の液晶フラット・ティスプレィ−パネルは
、液晶そのものが非発光体の為周囲が暗い場所では、＃
１とんど表示内容が見えないことより、第３図の様に、
液晶パネル１の下に、液晶パネル１と同じ大きさで一様
に発光する発光体３をひき、表示時にその発光体を点灯
することによシ８ｆ所での見にくさを数置していた。Conventionally, this German liquid crystal flat display panel does not emit light in dark surroundings because the liquid crystal itself is a non-luminescent material.
1.As shown in Figure 3, since the displayed content is not visible for the most part,
A light emitting body 3, which is the same size as the liquid crystal panel 1 and emits light uniformly, is placed below the liquid crystal panel 1, and the light emitting body is turned on when displaying, thereby making it difficult to see at 8F. .

必要とし、その発光体３は一般的に高電圧を必要とする
。また表示パネル面の大きさが大きくなるに伴ない消費
電力が大きくなり、長時間表示させる為には、比較的大
容量の電源が必要となるという欠点があった。The conventional light-emitting liquid crystal flat display panel described above requires a light emitter 3 having a size equivalent to the surface of the liquid crystal display panel, and the light emitter 3 generally requires a high voltage. In addition, as the size of the display panel surface increases, power consumption increases, and a relatively large capacity power source is required to display images for a long time.
