    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.
