Abstract

An electro-optical device includes a pixel column, a first and second data lines, and a first and second output circuits. The pixel column including pixel portions are arranged in a first direction. The first and second data lines extend in the first direction. The first and second output circuits output data voltages to different pixel portions of the pixel column through the first and second data lines, respectively.
