摘要： A data line driving section (6) 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 (6) 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 (4) 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.

摘要： Provided is a liquid crystal display device, including: a data line; a plurality of pixel circuits; an output grayscale value generating circuit for outputting an output grayscale value obtained by correcting a display grayscale value indicating a grayscale potential having one of positive polarity and negative polarity; and a data-line driving circuit for selectively outputting an output potential having one of positive polarity and negative polarity corresponding to the output grayscale value to the data line. The data-line driving circuit outputs the potential so that the positive-polarity output potential corresponding to a smallest output grayscale value becomes lower than a positive-polarity grayscale potential indicated by a smallest one of the display grayscale values and that the negative-polarity output potential corresponding to the smallest output grayscale value becomes higher than a negative-polarity grayscale potential indicated by the smallest one of the display grayscale values.
