A liquid crystal display element in which liquid crystal L is sealed between b, c... and a common counter electrode E facing the same, and the transparent electrodes a, b, c... of each display element 1, 2, 3... are respectively Input terminal X via resistors R 1 , R 2 , R 3 ...
are connected in parallel to each other, the other common counter electrode E is connected to the other terminal X', and each transparent electrode a, b,
c... and the common counter electrode E have a resistance R 10 ,
Connected via R 11 , R 12 .
そして抵抗R1〜５はR1＜R2＜R3…＜R5の如く
入力端子側より順次大とし、逆にR10〜15はR10＞
