Abstract
The present invention provides an electro-optical apparatus which, produce precharge signals PV,and PV,to be supplied to a precharge signal line using, for example, a differentiating circuit, outputs a peak at the rising edge or the falling edge of each signal with its successive portion progressively attenuating, and prevents the generation of luminance non-uniformity and chrominance non-uniformity attributed to parasitic capacitance and the like in a supply path of the precharge signal prior to the writing of an image signal.
