Patent ID: 8284181

Claim:
A display device comprising: a plurality of pixels; and a common electrode drive circuit, the common electrode drive circuit including a plurality of basic circuits, wherein the basic circuit comprises: a first circuit which latches a first input signal at a point of time that a clock signal is changed to a first voltage level from a second voltage level; a second circuit which latches a second input signal at the point of time that the clock signal is changed to the first voltage level from the second voltage level; a first switching circuit which is turned on based on the voltage latched by the first circuit and outputs a first power source voltage to an output terminal in an ON state; and a second switching circuit which is turned on based on the voltage which is latched by the second circuit and outputs a second power source voltage to an output terminal in an ON state, wherein when the first input signal assumes the second voltage level, the second input signal assumes the first voltage level, and when the second input signal assumes the second voltage level, the first input signal assumes the first voltage level, and after the clock signal is changed to the second voltage level from the first voltage level and before the clock signal returns to the first voltage level from the second voltage level, either one of the first input signal and the second input signal is changed to the second voltage level from the first voltage level.
