Patent ID: 8159435

Claim:
An active matrix type display device comprising: a first signal line and a second signal line arranged adjacent to each other along a given direction, wherein the signal lines are adapted to have video signals of a plurality of gradations applied thereto; a first pixel and a second pixel arranged between the first signal line and the second signal line and arranged adjacent to each other along the given direction; a third pixel arranged adjacent to the first pixel with the first signal line interposed between the first pixel and the third pixel and shared by the first pixel and the third pixel; a fourth pixel arranged adjacent to the second pixel with the second signal line interposed between the second pixel and the fourth pixel and shared by the second pixel and the fourth pixel; a first scanning line to which the first pixel and the fourth pixel are connected; a second scanning line to which the second pixel and the third pixel are connected; and a compensation circuit which causes only one pixel out of the first pixel and the second pixel to output a compensation video signal in which a signal compensation amount corresponding to a potential variation component is added or subtracted to compensate a video signal for the pixel, the potential variation component originating from an inter-pixel parasitic capacitance formed by the first and second pixels and generated between the first and second pixels when video signals of a same gradation are supplied via the first and second signal lines; wherein the compensation circuit, upon causing one of the first pixel and the second pixel to output the compensation video signal, causes the other of the first pixel and the second pixel to output a video signal that is not compensated by the signal compensation amount; and wherein the signal compensation amount is set to a constant value corresponding to the potential variation component generated when a gradation of a video signal is an intermediate tone, regardless of gradation values of the video signals applied to the first and second signal lines.
