Description
【考案の詳細な説明】
本考案は、液晶表示装置に関し、特に表示面を照射する
発光体からの光を、効率よく表示面に集中させたもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid crystal display device, in particular, to efficiently concentrate light from a light emitter that illuminates the display surface onto the display surface.
図は、本考案−実施例を示し、１は液晶表示パネルで、
スペーサ２により約１０μｍの間隔を保って２枚の透明
ガラス基板３，４が固定され、これら基板３，４間隙に
、ネマチック液晶５が充填されてなる。The figure shows an embodiment of the present invention, where 1 is a liquid crystal display panel;
Two transparent glass substrates 3 and 4 are fixed with a spacer 2 at a distance of about 10 μm, and the gap between these substrates 3 and 4 is filled with nematic liquid crystal 5.
６は、表示側透明基板３内面に形成された酸化スズＳｎ
Ｏ，膜等透明表示電極で、数字、文字表示パターン例え
ば田字型に配置されている。6 is tin oxide Sn formed on the inner surface of the display side transparent substrate 3.
Transparent display electrodes such as O, film, etc. are arranged in a display pattern of numbers and characters, for example, in a box shape.
７は、上記透明表示電極６に対向して、他の基板４内面
に形成された透明共通電極である。7 is a transparent common electrode formed on the inner surface of another substrate 4, facing the transparent display electrode 6.
８は、表示側基板３表面に配置された偏光板、９は、他
の基板４表面に配置された反射偏光板、１０は、偏光板
８上に液晶表示パネル１の表示面周囲に設けられた枠体
で、アルミニウム等にて構成される。Reference numeral 8 indicates a polarizing plate disposed on the surface of the display side substrate 3, numeral 9 indicates a reflective polarizing plate disposed on the surface of the other substrate 4, and numeral 10 indicates a polarizing plate disposed on the polarizing plate 8 around the display surface of the liquid crystal display panel 1. The frame is made of aluminum, etc.
この枠体１０の表示面側に位置する面は、表示面に相対
する方向に一定角度傾斜して形成され、さらにこの傾斜
面は、光を散乱反射するよう処理され、光反射面１１を
構成している。The surface of this frame body 10 located on the display surface side is formed to be inclined at a certain angle in the direction facing the display surface, and furthermore, this inclined surface is treated to scatter and reflect light, and forms a light reflecting surface 11. are doing.
１２は、枠体１０の一辺の略中央内側に形成された凹部
、１３はこの凹部１２内に配置された発光体で、例えば
発光ダイオード、豆ランプが使用できる。Reference numeral 12 denotes a recess formed on the inner side of the approximate center of one side of the frame body 10, and 13 represents a light emitting body disposed within the recess 12. For example, a light emitting diode or a miniature lamp can be used.
したがって、夜間等外光の乏しい場合には、発光体１３
を点灯すれば、これより放出された光は、枠体１〇四囲
の光反射面１１にて表示面側へ反射され、光の多くは、
表示側偏光板８を通って液晶表示パネル１へ入射する。Therefore, when there is little outside light such as at night, the light emitter 13
When turned on, the light emitted from it is reflected toward the display surface by the light reflecting surface 11 surrounding the frame 10, and most of the light is
The light passes through the display-side polarizing plate 8 and enters the liquid crystal display panel 1 .
これにより、外光が弱くとも、十分明瞭な表示を得るこ
とができる。Thereby, a sufficiently clear display can be obtained even if the external light is weak.
以上の説明のように本考案液晶表示装置は、液晶表示パ
ネルの前面に発光体を備えた枠体を設けさらにこの枠体
の内側には、表示パネルを照射すべく傾斜した光反射面
を形成したものであるがら、発光体より放出される光を
表示パネル側へ効率よく入射させることができ、明るい
表示パネルを得ることができる。As described above, the liquid crystal display device of the present invention includes a frame body equipped with a light emitting body in front of the liquid crystal display panel, and furthermore, an inclined light reflecting surface is formed inside the frame body to illuminate the display panel. However, the light emitted from the light emitting body can be efficiently incident on the display panel side, and a bright display panel can be obtained.
