本発明は不変嚢示を鮮かな色彩で見られるようにした液
晶表示素子に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid crystal display device that allows an unchanging display to be viewed in vivid colors.
従来の液晶表示素子では、不変表示を印刷により行う場
合、不透明インクを用いていたので、印刷個所が偏光板
と液晶との間に存在すると、インクにより光が散乱、し
ゃ断されろため、どのような色のインクを用いても、す
べて暗い色に見え、素子前面から見たときにはほとんど
黒色のように見えてしまうという欠点かあった。従って
、このように偏光板とセルの間に印刷する場合は具合表
示とし、黒色以外に見せたい場合は上偏光板の前面に印
刷していた。しかし、上偏光板の前面に黒以外の色で印
刷した場合、印刷表示と液晶表示との間の距離がやや長
いため、見る方向によって印刷表示と液晶表示との関係
位置がすれるという別の欠点が現れる。In conventional liquid crystal display elements, opaque ink is used when printing a permanent display, so if the printed area is between the polarizing plate and the liquid crystal, the ink scatters and blocks the light, so it is difficult to Even when ink of a different color was used, it all looked dark, and when viewed from the front of the element, it appeared almost black. Therefore, when printing between the polarizing plate and the cell in this way, it is used to indicate the condition, and when it is desired to appear other than black, it is printed on the front surface of the upper polarizing plate. However, if a color other than black is printed on the front surface of the upper polarizing plate, the distance between the printed display and the liquid crystal display is somewhat long, so there is another problem that the printed display and the liquid crystal display may be misaligned depending on the viewing direction. Shortcomings appear.
本発明の目的は上記の如き欠点のない、鮮かな色彩で印
刷により不変表示を行なった液晶表示素子を提供するこ
とにある。It is an object of the present invention to provide a liquid crystal display element that is free from the above-mentioned drawbacks and displays bright colors that are unchanged by printing.
上記目的を達成するために本発明においては、不変表示
を、元の散乱、しゃ断の少ない半透明インクを用いて、
偏光板と液晶セルとの間に印刷することとした。In order to achieve the above object, the present invention uses semi-transparent ink with less scattering and interruption for unchanging display,
We decided to print between the polarizing plate and the liquid crystal cell.

側面図で、図中、１は液晶セル、２は上偏光板、３は下
偏光板、４，４ａは半透明インク印刷による不変表示、
５は液晶表示、６は反射板である。Figure 1 (al is a front view of one embodiment of the present invention, (b) is a side view thereof, in which 1 is a liquid crystal cell, 2 is an upper polarizing plate, 3 is a lower polarizing plate, 4 and 4a are translucent Immutable display by ink printing,
5 is a liquid crystal display, and 6 is a reflective plate.
このように構成すれば、不変表示の印刷に用いた半透明
インクによる光の散乱およびしゃ断は少ないので、偏光
板および液晶層による旋光は損なわれず、インクの芭が
そのまま鮮かに表示され、不変表示４ａのように、黒い
液晶表示に背景の地色を印刷で重ね合わせることもでき
る。また印刷による表示と液晶表示の間の距離が知いた
め、見る方向による液晶表示と印刷衣７Ｆとの関係位置
ずれ色そのままの鮮かな色の表示が１１能となり、また
旋光性が損なわれないために、印刷（地色）部と液表示
との重ねイ（わせも可能となり、液晶表示菓子の多様化
に役立つ。With this configuration, the scattering and blocking of light by the translucent ink used to print the unchangeable display is small, so the optical rotation by the polarizing plate and the liquid crystal layer is not impaired, and the color of the ink is displayed clearly as it is, and the ink is not changed. As shown in display 4a, it is also possible to overlay the background color on a black liquid crystal display by printing. In addition, since the distance between the printed display and the liquid crystal display is known, it is possible to display vivid colors as they are due to the positional shift between the liquid crystal display and the printing cloth 7F depending on the viewing direction, and the optical rotation is not impaired. In addition, it becomes possible to overlap the printed (ground color) part and the liquid display, which helps diversify liquid crystal display confectionery.
