Patent ID: 7034276

Claim:
A driver circuit for driving an electro-optical device which has: a plurality of pixels; a plurality of scanning lines; a plurality of signal lines through each of which a multiplexed data signal for first to third color components is transmitted; and a plurality of demultiplexers, each of which includes first to third demultiplexing switch elements respectively controlled by first to third demultiplex control signals, one end of each of the demultiplexing switch elements being connected to one of the signal lines and the other end of each of the demultiplexing switch elements being connected to a pixel for the j-th color component (1≦j≦3, j is an integer) among the plurality of pixels, the driver circuit comprising: a gate signal generation circuit which generates a gate signal output to one of the scanning lines by using the first to third demultiplex control signals, wherein the gate signal generation circuit also generates a shift clock signal based on the first to third demultiplex control signals, shifts a start pulse signal based on the shift clock signal to obtain a shift output, and outputs a signal corresponding to the shift output to one of the scanning lines.
