Abstract
A liquid crystal display device includes a plurality of pixel circuits, data lines, and a data-line driving circuit connected to the data lines. Each of the pixel circuits includes a pixel capacitance having one end provided with a common potential. In accordance with a grayscale value for one of the plurality of pixel circuits, the data-line driving circuit selectively outputs a positive-polarity signal and a negative-polarity signal to the one pixel circuit. The data-line driving circuit outputs the positive-polarity signal and the negative-polarity signal so that an average of a potential of the positive-polarity signal and a potential of the negative-polarity signal corresponding to the grayscale value changes in accordance with the grayscale value, a temperature, and a position of the one pixel circuit.
