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.

Abstract: Second barrier electrodes are arranged under first barrier electrodes so as to fill gaps between the first barrier electrodes, while an insulating layer is located between the first barrier electrodes and the second barrier electrodes. The number of first barrier electrodes and the number of second barrier electrodes in each barrier pitch are 6 or more. The positions of the barriers formed by the first barrier electrodes and the second barrier electrodes are controlled by the reception of a signal representing detected positions of the eyes of a viewer. If pitches of the first barrier electrodes are defined as BE, and the widths of regions in which the first barrier electrodes are overlapped with the second barrier electrodes are defined as BA, a ratio BA/BE of the widths BA to the pitches BE are 0.3 or smaller. This configuration can suppress the occurrence of moire.
