Abstract
A liquid crystal device is formed by a pair of substrates, and a liquid crystal disposed between the substrates. At least one substrate has thereon a laminar structure including an electrode, an electrical property control layer and an alignment control layer contacting the liquid crystal disposed in this order on the substrate. The alignment control layer has a thickness of at most 100 .ANG., has been subjected to a uniaxial aligning treatment and has a volume resistivity larger than that of the electrical property control layer. The liquid crystal device thus constituted may exhibit a reduced influence of reverse electric field and a suppressed switching asymmetry over a wide temperature range.
