摘要： One frame of a video signal is separated to a plurality of display frames. To display a color specified by the video signal by mixing display colors of a plurality of display frames, the video signal is converted to data indicative of a voltage to be applied to each pixel over the display frames by using a conversion table. A voltage corresponding to the converted data is applied to a birifringence control type liquid crystal display device to drive the liquid crystal display device multiple times in one frame period of the video signal. When the response speed of the liquid crystal is fast, a color obtained by mixing the display colors of a plurality of display frames is recognized by an observer. When the response speed of the liquid crystal is slow, a color corresponding to an average value of the voltages applied to a plurality of display frames is recognized by the observer. When the liquid crystal has an intermediate response speed, a color obtained by visually mixing a series of display colors displayed during the transition of the alignment state of the liquid crystal is recognized by the observer.

摘要： A liquid crystal display device includes a liquid crystal cell including a liquid crystal layer twist-aligned at 90° sandwiched between a pair of substrates, first and second polarizing layers arranged to sandwich the liquid crystal cell therebetween so that their absorption axes set to parallel with directions crossing aligning treatment directions of the substrates at 45°, and viewing angle compensating plates respectively arranged between the polarizing layers and the liquid crystal cell. A total value of retardations in a thickness direction, defined as a value of a product of a phase difference within a plane perpendicular to substrate surfaces of the liquid crystal cell and a layer thickness, of optical layers present between the polarizing layers is set to a value that substantially cancels out a retardation in a liquid crystal layer thickness direction when a saturation voltage is applied to the liquid crystal layer.
