Liquid crystal device having interdigitated electrodes

摘要

This invention relates to a liquid crystal device applying an optoelectronic effect of liquid crystals. This invention aims at the provision of a liquid crystal device which is so constructed that; a transparent substrate having interdigital electrodes and a transparent substrate having an opposite electrode are disposed close to each other between two polarizers whose polarization axes intersect at a right angle with each other, so that both the electrodes are opposed to each other; a liquid crystal cell charging therein liquid crystal is disposed between both the transparent substrates so that the interdigital electrodes are arranged in parallel to the polarization axis of either one of two polarizers; the interdigital electrodes comprise a grounding electrode having a plurality of interdigital portions and a drive electrode positioned therebetween and having a width the same as that of one dot forming the ON and OFF conditions of the transmission light; and the drive electrodes are provided in plural rows, thereby having an extremely high contrast ratio for the ON and OFF conditions of the transmission light and responding at extremely high speed.
