Abstract:
1. A liquid crystal display device, comprising: a display area in which a plurality of pixels is arrayed; a plurality of video signal lines that extends in columns in the display area, and applies a video signal voltage based on a gradation value to the plurality of pixels; a first, a second, a third and a fourth inversion control signal lines each supplied with an inversion control signal for controlling inversion drive; a first selector that selects one of a first pair of amplifiers different in the polarity from each other to input signals corresponding to a first pair of adjacent video signal lines on the basis of the inversion control signal that is applied to the first inversion control signal line; a second selector that selects one of a second pair of amplifiers different in the polarity from each other to input signals corresponding to a second pair of adjacent video signal lines on the basis of the inversion control signal that is applied to the second inversion control signal line, a third selector that selects one of a third pair of amplifiers different in the polarity from each other to input signals corresponding to a third pair of adjacent video signal lines on the basis of the inversion control signal that is applied to the third inversion control signal line; and a fourth selector that selects one of a fourth pair of amplifiers different in the polarity from each other to input signals corresponding to a fourth pair of adjacent video signal lines on the basis of the inversion control signal that is applied to the fourth inversion control signal line, wherein inversion control signals to be applied to the four inversion control signal lines are different from each other.
