Description
【発明の詳細な説明】 本発明はカラー表示装置の表示面に関する。[Detailed description of the invention] The present invention relates to a display surface of a color display device.
従来のカラー表示装置はＣＲＴに代表される。A conventional color display device is typified by a CRT.
ＣＲＴでは、赤、青、緑の螢光体をデルタ形やストライ
ブ形に配して加色法によりカラー表示を行なっている。In a CRT, red, blue, and green phosphors are arranged in a delta shape or stripe shape, and color display is performed using an additive color method.
ＣＲＴの赤、青、緑の螢光体は単独に発光しているが、
人間の目はある程度離れて見ることにより、加色された
色を見ることができる。The red, blue, and green phosphors of a CRT emit light independently, but
Human eyes can see added colors by viewing from a certain distance.
それに対して現在ではカラー表示装置としてはＣＲＴに
加えて、液晶、螢光表示管、プラズマ等が考えられてい
る。新しいカラー表示装置は技術的問題や、コスト等か
ら、必ずしも各色表示画素を表示すイズに比較して細か
くすることができない。On the other hand, currently, in addition to CRT, liquid crystals, fluorescent display tubes, plasma, etc. are being considered as color display devices. New color display devices cannot necessarily make each color display pixel smaller than the display size due to technical problems, cost, etc.
言い換えれば、通常カラー表示装置を見る距離では完全
な加色法による表示ができなくなる。In other words, the distance at which a color display device is normally viewed does not allow complete additive color display.
本発明はかかる欠点を除去したもので、その目的は各色
表示の画素のピンチが荒くとも、完全な加色法によるカ
ラー表示装置を提供することにある。以下液晶カラー表
示装置に例を取り、本発明の詳細な説明する。The present invention eliminates such drawbacks, and its purpose is to provide a color display device using a complete additive coloring method even if the pixels for displaying each color are roughly pinched. The present invention will be described in detail below by taking a liquid crystal color display device as an example.
第１図は反射型の液晶カラー表示装置の断面図である。FIG. 1 is a sectional view of a reflective liquid crystal color display device.
図において１は反射板つき偏光板、２は下ガラス板、５

、７は光拡散板、８は光拡散面である。ガラス板には透
明電極とカラーフィルタが形成されている。第２図は液
晶カラー表示装置の画素拡大図である。In the figure, 1 is a polarizing plate with a reflector, 2 is a lower glass plate, and 5
4 is a liquid crystal layer, 4 is a sealing material, 5 is an upper glass plate, 6 is a polarizing plate, 7 is a light diffusing plate, and 8 is a light diffusing surface. A transparent electrode and a color filter are formed on the glass plate. FIG. 2 is an enlarged view of pixels of a liquid crystal color display device.
光拡散板の光拡散面の荒らさのピッチを画素のピッチよ
りある程度細かくすることによって、各カラーフィルタ
を透過した光が交差しあい、極めて近い位置でパネルを
見ても加色法によるフルカラー表示が得られる。By making the pitch of the roughness of the light diffusing surface of the light diffusing plate somewhat finer than the pixel pitch, the light that passes through each color filter intersects with each other, resulting in a full color display using the additive color method even when viewing the panel from a very close position. It will be done.
第６図は透過型の液晶カラー表示装五の断面図である。FIG. 6 is a sectional view of a transmissive liquid crystal color display device.
図において９は光源である。本実施例では前記効果に加
えて、光拡散板によって光が拡散されることによる視角
の増加という利点がある。In the figure, 9 is a light source. In addition to the above effects, this embodiment has the advantage of increasing the viewing angle due to the light being diffused by the light diffusing plate.
以」二のように本発明によれば、荒い画素ピッチでも加
色法によるフルカラー表示が可能である。As described above, according to the present invention, full color display using the additive coloring method is possible even with a rough pixel pitch.
言い換えれば、画素を荒くすると、ドライバーの減少、
表示体歩留りの向上等、低コスト化が可能である。また
、光拡散板を用いることによって視角の増加も可能であ
る。In other words, if you make the pixels coarser, the driver decreases,
It is possible to improve display yield and reduce costs. Furthermore, the viewing angle can be increased by using a light diffusing plate.
