Abstract
A data line driving section () outputs a video signal voltage for each pixel to a data line (DL) for each predetermined period in order. In outputting a video signal voltage for a pixel, the data line driving section () outputs a gradation signal voltage having a voltage corresponding to a gradation value of the pixel as the video signal voltage during a second part of the predetermined period, and outputs a correction gradation signal voltage different from the gradation signal voltage as the video signal voltage during a first part of the predetermined period. A control section () changes a relationship between the correction gradation signal voltage and the gradation signal voltage based on a combination of the gradation value of the pixel and a gradation value of a pixel preceding the pixel.
