Abstract
This invention relates to a liquid crystal device applying an optoelectronic effect of liquid crystal. This invention aims at the provision of a liquid crystal device comprising; a liquid crystal cell which has a transparent substrate having interdigital electrodes and a transparent substrate having an opposite electrode, the transparent substrates being disposed close to each other so as to allow both the electrodes to be opposite to each other, and which charges liquid crystal between both the transparent substrates; and a polarizer having polarization axis extending in parallel to the orientation of the liquid crystal caused by the electric field between the interdigital electrodes; thereby responding at high speed, having a high contrast ratio in ON and OFF conditions of the transmission light, and being small-sized and inexpensive to produce.
