この考案は、ＯＡ機器特にラップトップ・パソコン等の表示装置として用いら れる高精細なバックライト付き透過型単純マトリクス液晶表示装置に関する。 This idea can be used as a display device for office automation equipment, especially laptops and personal computers. This invention relates to a high-definition transmission type simple matrix liquid crystal display device with a backlight.

従来、図２に示すようにガラス基板１、ガラス基板２、偏光板３、アンチグレ ア処理がされていない偏光板１３およびドライバ回路５からなる液晶パネル、蛍 光管６、導光板７、光反射板８、平面レンズ９、拡散板１０およびスペーサ１１ からなるバックライトとケース１２から透過型単純マトリクス液晶表示装置が構 成されている。 Conventionally, as shown in FIG. 2, a glass substrate 1, a glass substrate 2, a polarizing plate 3, and an anti-glare A liquid crystal panel consisting of an untreated polarizing plate 13 and a driver circuit 5, a fluorescent Light tube 6, light guide plate 7, light reflection plate 8, plane lens 9, diffuser plate 10, and spacer 11 A transmission type simple matrix liquid crystal display device is constructed from a backlight consisting of a case 12 and a case 12. has been completed.

しかし、従来の透過型単純マトリクス表示装置は、蛍光管６の光１４が導光板 ７と反射板８で導光した後、発光面より発光するとき、平面レンズ９にて集光し 拡散板１０を介して液晶パネルに照射している。拡散板１０を使用する理由は、 平面レンズ９のレンズピッチと液晶パネルの画素ピッチが近いため干渉し、液晶 パネルの表示画像にもあれ縞が発生するのを防止するためである。拡散板１０の 使用は、その分製造価格の上昇と透過型単純マトリクス液晶表示装置の製造工程 数の増大および拡散板１０への静電気によるゴミの付着による品質不良による製 造歩留りの低下という課題があった。 However, in the conventional transmission type simple matrix display device, the light 14 from the fluorescent tube 6 passes through the light guide plate. After the light is guided by the light emitting surface 7 and the reflector 8, the light is focused by the plane lens 9 when emitted from the light emitting surface. The liquid crystal panel is irradiated via the diffuser plate 10. The reason for using the diffuser plate 10 is The lens pitch of the plane lens 9 and the pixel pitch of the liquid crystal panel are close, so there is interference, and the liquid crystal This is to prevent irregular stripes from appearing in the image displayed on the panel. of the diffuser plate 10 This increases the manufacturing cost and reduces the manufacturing process of transparent simple matrix liquid crystal display devices. Due to poor quality due to increase in number and adhesion of dust due to static electricity to the diffuser plate 10. There was a problem of decreased manufacturing yield.
【０００４】 そこで、この考案の目的は、従来のこのような課題を解決するため、製造工程 数と製造費用の削減および製造歩留り向上を得ることである。0004 Therefore, the purpose of this invention was to improve the manufacturing process in order to solve these conventional problems. The objective is to reduce the number and manufacturing costs and improve manufacturing yield.

上記課題を解決するために、この考案は、透過型単純マトリクス液晶表示装置 において、偏向板のバックライトモジュール側の面にアンチグレア処理を施して 、偏光板に拡散板の機能を兼ね備えることにより、拡散板１０を削除することが できた。 In order to solve the above problems, this invention is a transmission type simple matrix liquid crystal display device. In this case, anti-glare treatment is applied to the backlight module side surface of the deflection plate. By combining the polarizing plate with the function of a diffusion plate, the diffusion plate 10 can be removed. did it.

上記のように構成された透過型単純マトリクス液晶表示装置においては、レン ズ９を透過した光１４は本発明の偏向板４（図１参照）のアンチグレア処理面に て拡散されるので、液晶パネルの表示画像にもあれ縞が発生することはない。従 って、偏光板に拡散板の機能を代用させるため拡散板１０が不用となり、拡散板 の使用を廃止できることとなる。 In the transmission type simple matrix liquid crystal display device configured as described above, the lens The light 14 transmitted through the lens 9 is directed to the anti-glare treated surface of the deflection plate 4 (see FIG. 1) of the present invention. Since the light is diffused by the light, no stripes will appear on the displayed image on the liquid crystal panel. subordinate Therefore, the diffuser plate 10 is no longer needed because the polarizing plate is used as a substitute for the function of the diffuser plate. This means that the use of can be abolished.

以下に、この考案の実施例を図１に基づいて説明する。 図１において、ガラス基板１、ガラス基板２、偏光板３、アンチグレア面を有す る偏光板４およびドライバ回路５を有する液晶パネル（両ガラス基板間の液晶層 等一部図示省略してある）と蛍光管６、導光板７、光反射板８、平面レンズ９お よびスペーサ１１からなるバックライトモジュールとケース１２とから透過型単 純マトリクス液晶表示装置が構成されている。 An embodiment of this invention will be described below based on FIG. 1. In FIG. 1, a glass substrate 1, a glass substrate 2, a polarizing plate 3, and an anti-glare surface are shown. A liquid crystal panel having a polarizing plate 4 and a driver circuit 5 (liquid crystal layer between both glass substrates) etc. are partially omitted), fluorescent tube 6, light guide plate 7, light reflection plate 8, flat lens 9 and A transmission type unit is formed from the backlight module consisting of the spacer 11 and the case 12. A pure matrix liquid crystal display device is constructed.
【０００８】 本発明に係る偏光板４は、バックライトモジュール側の面がアンチグレア処理 されているので、バックライトモジュールからの光はこのアンチグレア処理面に て拡散する。そこで、平面レンズ９のレンズピッチと液晶パネルの画素ピッチが 近いため干渉する原因が取り除かれ、液晶パネルの表示画像にもあれ縞が発生す るのを防止できる。[0008] The polarizing plate 4 according to the present invention has an anti-glare treatment on the backlight module side surface. so the light from the backlight module is directed onto this anti-glare treated surface. and spread. Therefore, the lens pitch of the plane lens 9 and the pixel pitch of the liquid crystal panel are Because they are close together, the cause of interference is removed and stripes do not appear on the display image on the LCD panel. You can prevent this from happening.
