PROBLEM TO BE SOLVED: To surely suppress the degradation of image quality when driving a liquid crystal display device at a high refresh rate.SOLUTION: A data line drive part 6 outputs the video signal voltage of each pixel to a data line DL in the order by a predetermined period each. In this case, when outputting the video signal voltage of a certain pixel, the data line drive part 6 outputs a gradation signal voltage having a voltage corresponding to the gradation value of the pixel as the video signal voltage in the second half period of the predetermined period, and outputs a correction gradation signal voltage different from the gradation signal voltage as the video signal voltage in the period before the above period. In this case, a control part 4 changes a relation between the correction gradation signal voltage and the gradation signal voltage, according to the combination of the gradation value of the pixel and the gradation value of the pixel preceding the pixel in order. |
