摘要：
A liquid crystal driver is provided, in which a frame rate of an input image signal is multiplied by 2N (N is an integer of one or more); each frame is divided into N positive field(s) and N negative field(s) respectively; the image signal is supplied to a liquid crystal panel with a positive polarity in a positive field; and the image signal is supplied to the liquid crystal panel with a negative polarity in a negative field. The liquid crystal driver includes a corrected image signal generator configured to generate a corrected image signal having the same amount of correction added to the positive field and negative field. The corrected image signal is supplied to the liquid crystal panel with the positive polarity in the positive field and the corrected image signal is supplied to the liquid crystal panel with the negative polarity in the negative field.
