Abstract

PURPOSE:To facilitate a reversal display of the data and hour in a watch, etc. by laying 2 liq. crystal layers and placing an electrode which reverses the display of one layer to the other layer when a voltage is applied. CONSTITUTION:A liq. crystal display element is formed in 2 layers, and the orienting directions of orienting films 3 attached to the insides of upper and lower glass plates 1 are made parallel to each other and parallel to the polarizing axes of upper and lower polarizing plates 6. The orienting directions of orienting films 3 attached to the upper and under surfaces of a middle glass plate 1 are made parallel to each other and perpendicular to the orienting direction of the films 3 attached to the insides of the upper and lower glass plates 1. A transparent electrode 2 under the upper plate 1 is a plane one, and a transparent electrode pattern enabling a digital display is set on the upper surface of the middle plate 1. Transparent electrodes 2 covering part of the display section are placed on the under surface of the middle plate 1 and the upper surface of the lower plate 1 opposite to each other. Using this liq. crystal display element a white segment display of a specified data on the black ground for a watch, etc. or a positive or negative display for an electronic desk calculator, etc. is carried out easily.
