Abstract
An electro-optical device includes a scan line, a data line, a pixel circuit provided at an intersection of the scan line and the data line, a first high potential line, a first low potential line, a second high potential line, and a second low potential line. The pixel circuit includes a light emitting device, a memory circuit disposed between the first high potential line and the first low potential line, a first transistor of N-type including a gate electrically connected to the memory circuit, and a second transistor disposed between the memory circuit and the data line. The light emitting device and the first transistor are disposed in series between the second high potential line and the second low potential line.
