Patent ID: 8427401

Claim:
An electro-optical device, comprising: a plurality of element driving lines extending at an interval between the lines; a plurality of unit circuits arranged corresponding to intersections between the plurality of element driving lines and a plurality of data lines; an element driving circuit which sequentially supplies a first potential to the element driving lines during a period of driving in each unit period; and a data line driving circuit which outputs to each of the data lines a data potential during a period of writing before the period of driving in each unit period, the data potential corresponding to gray scale data of the unit circuit for the element driving line supplied with the first potential during the period of driving in the unit period, wherein each of the plurality of unit circuits includes a capacitive element which has a first electrode as a reference potential and a second electrode connected to one of the data lines, and an electro-optical element which has a third electrode connected to the second electrode and a fourth electrode connected to one of the element driving lines and has a gray scale level corresponding to the data potential, and wherein the electro-optical element is driven in such a manner that a potential difference, which is defined by the difference between the first potential and the data potential accumulated in each of the capacitive elements in each of the unit circuits along the one data line, is generated between the third electrode and the fourth electrode by supplying the first potential to the element driving line.
