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.
