Abstract
An electro-optical device includes pixels and a power supply circuit. The pixels are provided at positions corresponding to intersections of a plurality of scanning lines and a plurality of data lines. Each of the pixels includes a pixel switching element that is connected to a corresponding one of the data lines, a corresponding one of the scanning lines and a pixel electrode. When the scanning line connected to the pixel switching element is selected, the corresponding pixel electrode enters a conductive state with a corresponding one of the data lines. The power supply circuit generates a power supply electric potential for controlling on/off of each pixel switching element. The power supply circuit includes a discharging resistance that has a resistance value such that an electric current that is sufficiently smaller in comparison with the feeding capability of the power supply circuit in a steady state flows through an output portion of the power supply electric potential.
