Patent ID: 7830347

Claim:
A liquid crystal display device including a plurality of drain signal lines, a plurality of gate signal lines arranged to intersect said plurality of drain signal lines, and a plurality of thin film transistors disposed in vicinities of intersections of said plurality of drain signal lines and said plurality of gate signal lines and coupled to corresponding ones of said plurality of drain signal lines and said plurality of gate signal lines, and a drain driver which supplies signal voltages to said plurality of drain signal lines, said drain driver comprising: an amplifier circuit which outputs a signal voltage to a corresponding one of said plurality of drain signal lines; wherein said amplifier circuit includes a switching circuit which switches between a first state and a second state, said first state being a state where a first input terminal of said amplifier circuit is coupled to an inverting input terminal and a second input terminal is coupled to a noninverting input terminal, and said second state being a state where said first input terminal is coupled to said noninverting input terminal and said second input terminal is coupled to said inverting input terminal; and wherein said signal voltages supplied to said plurality of thin film transistors coupled to a given one of said plurality of gate signal lines, via said plurality of drain signal lines are gray scale voltages one of plus and minus offset voltages in a first frame, and are gray scale voltages one of plus and minus said offset voltage in a second frame.
