Patent ID: 8686930

Claim:
An electro-optical device, comprising: a plurality of scanning lines, each scanning line including at least two or more wirings; a plurality of data lines intersecting the scanning lines; a plurality of unit circuits, each unit circuit: being disposed at an intersection of one of the wirings of one of the scanning lines and one of the data lines, being connected to the one of the wirings and the one of the data lines, and corresponding to a unit period including a driving period and a writing period; a data line drive circuit that outputs a plurality of data potentials to only some of the data lines, in response to gradation data of the corresponding unit circuits connected to the corresponding data line, during the first half of a unit period of a unit circuit, and outputs a plurality of data potentials to the other data lines during a second half of a unit period of each unit circuit; and a scanning line drive circuit that sequentially selects one of the wirings of one of the scanning lines during one of the driving periods of one of the unit circuits, wherein each of the plurality of unit circuits includes: an electric optical element that displays gradation in response to the data potential; and a capacitative element having a first electrode and a second electrode; and a switching element that is electrically connected between the second electrode and the electric optical element, wherein the first electrode of the capacitative element is directly connected to a capacitance line without being connected to the switching element, and the second electrode of the capacitative element is directly connected to the data line, and wherein the capacitance line receives a fixed, non-grounding potential.
