摘要:
A liquid crystal display device includes drain signal lines, gate signal lines, thin film transistors, and a drain driver. The drain driver includes an amplifier circuit having a switching circuit which switches between a first state and a second state, the first state being a state where a first input terminal of the amplifier circuit is coupled to an inverting input terminal and a second input terminal is coupled to a noninverting input terminal, and the second state being a state where the first input terminal is coupled to the noninverting input terminal and the second input terminal is coupled to the inverting input terminal. The amplifier circuit supplies signal voltages to the thin film transistors via the drain signal lines which are gray scale voltages one of plus and minus offset voltages in a first frame and in a second frame.
