Abstract: There is provided a circuit for driving an electro-optical device having a precharge voltage generating circuit. The precharge voltage generating circuit has a subtracter for obtaining a difference between a gray scale level of each of pixels which is disposed along one of scanning lines and a reference gray scale previously set, an integrator for integrating the subtraction result for the pixels of one row which are disposed along the one of the scanning lines, an adder for adding a reference value of a precharge voltage to the integrated value, a D/A converter for converting a voltage corresponding to the added result into an analog signal, and an inversion circuit for outputting a precharge signal Vpre which is obtained by inverting the analog signal corresponding to writing polarity.
