Patent ID: 8159480

Claim:
An electro-optical device comprising: a plurality of scanning lines and a plurality of data lines; pixels arranged so as to correspond to intersections of the plurality of scanning lines and the plurality of data lines; and an electro-optical material in which a response speed at a time of changing to halftone display is lower than those at a time of changing to low-gray-scale-level display and at a time of changing to high-gray-scale-level display, wherein each of the pixels includes at least two adjacent subpixels as a group, each of the subpixels including a pixel electrode, a common electrode arranged so as to face the pixel electrode, and a switching device which electrically connects a corresponding one of the data lines to the pixel electrode in accordance with a selection voltage supplied from a corresponding one of the scanning lines, the switching device being connected to the corresponding one of the scanning lines.
