ABSTRACT:
A liquid crystal display element includes a pattern display section defined by the superposing portions of upper and lower display electrodes. In a non-display area around the display section, upper and lower non-display electrodes are arranged so that the superposing portion thereof partially or entirely covers the non-display area. In operation, a non-selective voltage is always applied across a liquid crystal at the superposing portion of the upper and lower non-display electrodes.
