Abstract
An electro-optical device a pixel circuit located at a position corresponding to an intersection of a scan line and a data line, a first potential line supplies a first potential, a second potential line supplies a second potential, and a third potential line supplies a third potential. The pixel circuit includes a light emitting element and a memory circuit. The memory circuit that is disposed between the first potential line and the second potential line, and that includes a first transistor. A source of the first transistor is electrically connected to the first potential line. The light emitting element is disposed between a drain of the first transistor and the third potential line. An absolute value of a potential between the first potential and the second potential is smaller than an absolute value of a potential between the third potential and the second potential.
