Abstract
A liquid crystal device includes a pair of transparent substrates disposed with a prescribed gap therebetween and each having a transparent electrode thereon, a photoelectric conversion semiconductor layer not subjected to rubbing formed on one of the pair of transparent substrates, and alignment film subjected to rubbing formed on the other of the pair of transparent substrates, an a liquid crystal disposed between the photoelectric conversion semiconductor layer and the alignment film. As the photoelectric conversion semiconductor is freed from an aligning performance, the material thereof is freed from the constraint and can be selected so as to optimize the photoelectric conversion performance.
