Liquid crystal device, electronic device and projector with maximum-light-intensity direction inclined from the direction normal to the substrates

摘要

A liquid crystal device includes a liquid crystal panel including a pair of substrates that sandwiches a liquid crystal layer containing liquid crystal molecules exhibiting a parallel alignment in an initial alignment state, and a polarizing plate disposed on either side of the liquid crystal panel. The liquid crystal molecules are inclined at a pretilt angle and aligned in a predetermined direction in planes of the substrates. The liquid crystal panel emits light entering through one of the polarizing plates toward the other. The liquid crystal panel emits light having the maximum intensity in a direction different from a direction normal to the substrates. The azimuth of the maximum-light-intensity direction projected onto the planes of the substrates is substantially parallel to the predetermined direction. The maximum-light-intensity direction is a direction inclined from the direction normal to the substrates toward a direction in which the maximum-light-intensity direction form a right angle with a longitudinal direction of the liquid crystal molecules inclined at the pretilt angle.
