Document Type and Number:
Japanese Patent JP2952150
Kind Code:
B2
Abstract:
A liquid crystal device is constituted by a pair of substrates, and a chiral smectic liquid crystal assuming at least two stable states disposed between the two substrates. At least one of the substrates is subjected to a uniaxial aligning treatment in two directions including a normal direction and a reverse direction substantially opposite to the normal direction. The liquid crystal is placed in an alignment state such that the liquid crystal provides an apparent tilt angle theta a which is a half of an angle between said two stable states, a tilt angle H/ &cir& and a pretilt angle alpha with respect to a substrate surface, and forms smectic layers forming an inclination angle delta from a normal to the substrate surfaces, satisfying: H/ &cir& /2 < theta a alpha + delta . According to the liquid crystal device, an undesirable liquid crystal molecular movement along the substrates is effectively suppressed.
