本発明は、ネガテイブ表示の地色部分に見苦し
い白抜け個所が点在しないようにした液晶表示素
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

ことが行なわれており、従来はネガテイブ表示素
子にも透明なガラスフアイバが用いられていた。
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

光板の偏光軸が平行なネガテイブ表示素子の場
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に、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つた。 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.
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 spacer, resulting in an unsightly display with small white spots scattered in areas 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

ことにある。 SUMMARY OF THE INVENTION An object of the present invention is to provide a negative display liquid crystal display element which does not have the above-mentioned problems and which prevents white spots from being scattered in the background color area and provides a clear display.
上記目的を達成するために本発明においては、

を、目立たないようにした。 In order to achieve the above object, in the present invention,
By using colored rather than transparent spacers to maintain the distance between opposing display electrode surfaces at a predetermined value, the amount of light passing through the spacers that is present in the display background in the display area can be reduced. The spacer intervening area, which used to be easily noticeable, has been made less noticeable.

形成時に添加すればよい。 Hereinafter, FIG. 1, which shows a cross section perpendicular to the display surface of an embodiment of the present invention, will be described. In the figure, 1 is an upper and lower substrate with transparent display electrodes and alignment films formed on the inner surface, 2 is an upper and lower polarizing plate having polarization axes parallel to each other, and 3 is a TN (Twisted Nematic) type liquid crystal. 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 no white spots will occur even in the spacer-interposed area. Good results were obtained when the glass fiber was colored with black or blue. To make the fiber black, a mixture of trivalent chromium, trivalent nickel, manganese, etc. may be added, and to make it blue, cobalt may be added at the time of fiber formation.
