ABSTRACT:
A ferroelectric liquid crystal device in which a ferroelectric liquid crystal is interposed between a pair of electrode substrates facing each other, and in which pixels are formed at intersections of upper and lower electrodes. A threshold gradient is provided in each pixel, and a light-shielding electrode portion is formed along at least a part of the periphery of each pixel so that no domain wall is formed at the boundary between the shielding electrode portion and a pixel portion adjacent to the shielding electrode portion.
