Abstract
A semiconductor integrated circuit including a first register which latches display data, a second register which latches the display data of the first register in accordance with a first clock, a gray scale voltage generator which outputs a plurality of gray scale voltages, a decoder which selects a gray scale voltage in accordance with the display data of the second register from the plurality of gray scale voltages, and an amplifier including a first transistor and a second transistor. A first terminal of the first transistor and a first terminal of the second transistor are connected to a first voltage line, and the gray scale voltage outputted from the decoder is supplied to one of input terminals of the first transistor and the second transistor in accordance with a control signal. A phase of the control signal is reversed at intervals of two horizontal scanning lines.
