摘要： An LUT fixedly stores correction values to compensate for a pull-in voltage in pixels in a liquid crystal panel. In at least one example embodiment, the display control unit outputs an input video signal Xa, a video signal Xp of a previous frame read from a frame memory, and a pixel polarity indicating a polarity of a pixel applied voltage on the pixel basis, and outputs a correction value read from the LUT to a data line driving circuit as a video signal Xb after correction. The data line driving circuit performs alternate current driving, based on the video signal Xb after correction. The LUT stores different correction values between when a positive polarity voltage is applied and when a negative polarity voltage is applied, for at least a part of combinations of values of the input video signal Xa and the video signal Xp of the previous frame. This can reduce a difference in response speed between when the positive polarity voltage is applied and when the negative polarity voltage is applied, thereby enhancing display quality.

摘要： A pixel includes a plurality of first linear alignment regulating structures (22) provided on the liquid crystal layer side of a first substrate and a plurality of second linear alignment regulating structures (44) provided on the liquid crystal layer side of a second substrate. The first and second linear alignment regulating structures each have a first component (22a, 44a) extending along a first axis and a second component (22b, 44b) extending along a second axis which is different from the first axis, the second linear alignment regulating structures being linear dielectric protrusions. The liquid crystal display device further includes a connection dielectric protrusion (45a, 45b, 45c) for interconnecting two linear dielectric protrusions which belong to pixels adjoining each other and which are not collinear. The connection dielectric protrusion has a plurality of edges, the plurality of edges including at least one edge extending in a direction which is different from the direction of an edge of the first electrode (21) and different from the direction of an edge of the linear dielectric protrusion. According to the present invention, an enhanced design freedom can be obtained without deteriorating the display quality of an MVA-mode liquid crystal display device.
