Abstract

A liquid crystal display device includes a plurality of video signal lines that extends in columns in a display area, a plurality of inversion control signal line each supplied with an inversion control signal for controlling inversion, a first selector that selects one of a pair of amplifiers different in the polarity from each other to input signals corresponding to a pair of adjacent video signal lines on the basis of the inversion control signal, and a second selector that selects one of a pair of the corresponding adjacent video signal lines to input signals output from the pair of amplifiers on the basis of the inversion control signal, in which at least one of the signals to be supplied to the plurality of inversion control signal lines is a signal different from other signals.

Claims (15)

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.

2. The liquid crystal display device according to claim 1 ,

wherein the at least one inversion control signal is a signal different in cycle from the other inversion control signals.

3. The liquid crystal display device according to claim 1 ,

wherein the at least one inversion control signal is a signal identical in cycle and different in phase from the other inversion control signals.

4. The liquid crystal display device according to any one of claims 1 to 3 ,

wherein a pixel array in the display area is a delta pixel array.
