Liquid crystal device and display apparatus including the device
摘要:
A liquid crystal device comprises chiral smectic liquid crystal, two substrates and electrodes for applying a voltage to the liquid crystal to form pixels, each provided with an active element connected to an associated electrode on at least one substrate. The liquid crystal alignment forms domains D1 and D2, wherein the liquid crystal is aligned to provide an average molecular axis in a monostable alignment state under no voltage application, is tilted from such state in one direction when supplied with a voltage of a first polarity at a tilting angle which varies with the magnitude of the supplied voltage, and is tilted in the other direction when supplied with a voltage of a second and opposite polarity. Maximum tilting angles &bgr;1 and &bgr;2, formed under application of the voltages of the first and second polarities, respectively, satisfy: &bgr;1>&bgr;2>0 in domain D1 and 0
