ABSTRACT:
A liquid crystal optical device of this invention includes one substrate having a substrate surface on which one electrode is formed, the other substrate having a substrate surface on which the other electrode is formed, a first aligning film covering one electrode of one substrate and at least a portion of the substrate surface, a second aligning film covering the other electrode of the other substrate and at least a portion of the substrate surface, a dielectric layer disposed between at least one of the first and second aligning films and the electrode corresponding thereto, a sealing member for bonding the one substrate and the other substrate to each other with a predetermined gap therebetween to oppose the substrate surfaces of the one and the other substrates on which the electrodes are formed, and sealing the gap, and a ferroelectric liquid crystal material sealed in the gap surrounded by one and the other substrates disposed oppositely and the sealing member. The dielectric layer is formed of a metal oxide film having approx. 20 dyn/cm or more of polar power component of its surface energy.
