Patent ID: 7705839

Claim:
A driving circuit for an electro-optical device which drives an electro-optical device having a plurality of data lines and a plurality of scanning lines extending to cross each other, and a plurality of pixel electrodes arranged in an image display region corresponding to intersections of the data lines and the scanning lines, the driving circuit for an electro-optical device comprising: a shift register that has stages each of which generates a transfer signal for defining writing timing and sequentially outputs the transfer signal from the corresponding stages; a precharge supply line that supplies a precharge timing signal for defining precharge timing ahead of the writing timing; a precharge circuit that receives the precharge timing signal and outputs a timing signal; and a data line circuit that receives the timing signal, shapes the timing signal on the basis of at least the transfer signal, and drives the plurality of data lines according to the timing signal, the data line circuit including: a first enable supply line that supplies plural series of first enable signals having a first pulse width narrower than that of the timing signal outputted based on at least the transfer signal; a second enable supply line that supplies one series of second enable signals having a second pulse width narrower than the first pulse width; and an enable circuit to which the timing signal and the first and second enable signals are inputted, that shapes the respective pulses of the timing signal on the basis of the plural series of first enable signals to limit the pulse width of the timing signal to the first pulse width, and that shapes all pulses of the timing signal on the basis of the one series of second enable signals, after being limited to the first pulse width, so as to limit the pulse width of the timing signal to the second pulse width.
