Abstract: According to an aspect, a display device has a first electrode, a second electrode and liquid crystal layer. When a voltage is not applied to the first and second electrodes, the major axes of the liquid crystal molecules are oriented in a third direction. When a voltage is applied between the first and second electrodes, the major axes are oriented so as to rise in a direction perpendicular to a first substrate while rotating clockwise in a vicinity of one of long sides of comb tooth portion that face each other and counterclockwise in a vicinity of the other of the long sides. An angle between an electrode base-side portion of a long side of each comb tooth portions and the third direction is larger than an angle between a distal end-side portion of the long side of each comb tooth portions and the third direction.

Abstract: A pixel electrode formed into a slit structure with striped electrodes opposed to each other for a zero rubbing angle can provide fast response since rotational directions of the liquid crystals become opposite at both sides of the slit in the striped electrodes. The electrode structure, however, poses a problem of low transmittance. Provided is a liquid crystal display device of IPS-Pro scheme including a pixel electrode with one pair of striped electrodes. The first striped electrode includes a short electrode section and long electrode sections, and the second striped electrode also includes a short electrode section and long electrode sections. The long electrode sections of the first striped electrode are disposed adjacently to those of the second striped electrode. Liquid crystals are aligned in a lengthwise direction of the striped electrodes.
