Abstract

A driving circuit for an electro-optical device 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 includes a shift register that has stages each of which generates transfer signals for defining writing timing and sequentially outputs the transfer signals from the respective stages, a precharge supply line that supplies a precharge timing signal for defining precharge timing ahead of the writing timing, 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.
