液晶表示装置およびその製造方法
Document Type and Number:
Japanese Patent JP5570829
Kind Code:
B2
Abstract:
A liquid crystal device comprises two electrodes 30,40 parallel to each other formed on one 10 of two substrates 10,20, homeotropic alignment films 90 formed on the substrates and a liquid crystal material 70 having positive dielectric anisotropy injected between the substrates. When a voltage V is applied to the two electrodes, a parabolic electric field between the electrodes drives the liquid crystal molecules. Since the generated electric field is symmetrical with respect to the boundary-plane equidistant from each of the two electrodes, the liquid crystal molecules 80 are symmetrically aligned with respect to the boundary-plane, and the optical characteristic is compensated in both regions divided by the boundary-plane, thereby obtaining a wide viewing angle. The electric field does not exert any influence on the liquid crystal molecules on the boundary-plane since the electric field on the boundary-plane is parallel to the substrate and perpendicular to the two electrodes; and thus, it is perpendicular to the liquid crystal molecules. The device also comprises means for varying directions of long axes of molecules of the liquid crystal layer, wherein the layer has at least two adjacent regions, the molecules of any one region being aligned in the same direction, and the molecules of two regions are aligned symmetrically with respect to the plane-boundary of the regions. The parallel electrodes in each pixel unit may be bent, and in adjacent pixels may be in different directions.
