Abstract

PURPOSE:To prevent a TN type liquid crystal negative display element from being dotted with minute white omission parts, by using a colored glass fiber pieces as gap holding spacers between upper and lower substrates and reducing the quantity of the light passing through glass fibers. CONSTITUTION:Glass substrates 1 which have polarizing plates on outside faces and have transparent electrodes and oriented films on inside faces are used as upper and lower substrates. Colored glass fiber pieces are used as spacers 4 for the purpose of keeping the gap between upper and lower substrates constant. A TN type liquid crystal 3 is sealed through colored glass fiber spaces 4 to obtain a negative liquid crystal display element where data is displayed with white characters in a thick color such as a black color. The quantity of the light passing through spacers 4 is absorbed by colored glass fiber spacers 4 and is reduced, and thus, white omission is not generated even in positions where spacers 4 are interposed.

Description

【発明の詳細な説明】 本発明は、ネガティブ表示の地色部分に見苦しい白抜は
個所が点在しないようＫした液晶表示素子に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid crystal display element in which unsightly white spots are not scattered in the background color portion of negative display.

液晶表示素子では、その狭い上、下基板間の間隔を保持
させるためのスペーサとして、透明なガラスファイバ片
を、これら基板の間に分散させることが行なわれ【おり
、従来はネガティブ表示素子にも透明なガラスファイバ
が用いられていた。In liquid crystal display elements, pieces of transparent glass fiber are dispersed between the substrates as spacers to maintain the narrow distance between the upper and lower substrates. A transparent glass fiber was used.

しかし、このスペーサの介在する個所では上、下基板間
に液晶が存在せず、直線偏光は偏光軸を旋回されること
なく通過してしまうので、上、下偏光板の偏光軸が平行
なネガティブ表示素子の場合、スペーサ介在個所は光が
通過できることとなり、地色となるべき領域ｋ、こまか
な白抜けが点在する見苦しい表示となるという問題があ
った。However, where the spacer exists, there is no liquid crystal between the upper and lower substrates, and linearly polarized light passes through without being rotated around the polarization axis. In the case of a display element, light can pass through the area where the spacer is interposed, resulting in an unsightly display with small white spots scattered in the area k that should be the background color.

本発明の目的は上記問題のない、地色領域に白抜けが点
在するのを防止した、きれいな表示の得られるネガティ
ブ表示の液晶表示素子を提供することにある。An object of the present invention is to provide a negative display liquid crystal display element which does not have the above-mentioned problems, prevents white spots from being scattered in the background color area, and provides a clear display.

圧した。In order to achieve the above object, the present invention uses a colored rather than a transparent glass fiber for the spacer to reduce the amount of light passing through the glass fiber, making the spacer intervening area, which was easily noticeable in the past, less noticeable. I felt a lot of pressure.

ァイバ形成時に添加すればよい。A lower substrate, 2 are upper and lower polarizing plates having polarization axes parallel to each other, 3 is a liquid crystal, and 4 is a spacer made of a piece of colored glass fiber according to the present invention. By carrying out the present invention, the amount of light passing through the spacer is reduced due to absorption by the colored glass fiber, and white spots will not occur even in the spacer-interposed area. Black or gastric coloring of the glass fiber showed good results. To make it black, use trivalent rims. To make the mixture of trivalent nickel and mango/I blue, cobalt may be added at the time of fiber formation.

本発明は、ネガ形カラー液晶表示素子にも実施すること

に着色したガラスファイバ片をスペーサにすればよい。The present invention can also be implemented in a negative color liquid crystal display element, and the spacer may be a piece of glass fiber colored in the same color as the dichroic dye added to the color liquid crystal.

以上説明したように本発明によれば、ネガティブ表示の

る。As explained above, according to the present invention, it is possible to prevent a large number of minute white spots caused by spacers from being scattered in the background color portion of a negative display, and the appearance of the display becomes clear.
