Abstract
A liquid crystal optical device is comprised of a liquid crystal layer and a pair of substrates for sandwiching the liquid crystal layer to effect orientation of molecules of the liquid crystal layer. A plurality of base electrodes are disposed on an inner surface of one of the substrates. A plurality of color filter films are electrodeposited on the respective ones of the base electrodes and have different color tones. A plurality of driving electrodes are disposed on the color filter films for applying a driving voltage to the liquid crystal layer. A protective layer is interposed between the color filter films and the driving electrodes to effect buffering of thermal stress caused therebetween.
