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: To achieve a liquid crystal display device of a field sequential system with sufficient response speed and uniformity of viewing angle, the liquid crystal display device includes polarizing plates attached on front and back surfaces of a liquid crystal display panel, a backlight provided on the back surface of the liquid crystal display panel, and an anisotropic diffusion film provided on the front side of the liquid crystal display panel. The liquid crystal display panel and the backlight are driven by the field sequential system. The distribution of the contrast of the liquid crystal display panel varies depending on the azimuth direction. Then, the azimuth direction in which the contrast of the liquid crystal display panel is small is equal to the azimuth direction in which the emission intensity when parallel light is incident on the anisotropic diffusion film is strong, to achieve uniform contrast in all azimuth directions.
