Abstract
An electro-optical device includes a pixel circuit provided to correspond to an intersection of a scan line and a data line, a low potential line, and a high potential line. The pixel circuit includes a light emitting element, a first transistor, and a memory circuit including a first inverter, a second inverter, and a second transistor. The first transistor is disposed between an first input terminal of the first inverter and the data line. The second transistor is disposed between an second output terminal of the second inverter and the first input terminal. An first output terminal of the first inverter is electrically connected to an second input terminal of the second inverter. When the first transistor is in an ON-state, the second transistor is in an OFF-state.
