Abstract
A method of driving a pixel circuit is provided. The pixel circuit includes a light emitting element that emits light by receiving a driving current, a driving transistor that generates the driving current, and a light-emission control transistor of the same conductivity type as that of the driving transistor, the light-emission control transistor being arranged on a path through which the driving current flows from the driving transistor to the light emitting element. The method includes setting the gate potential of the light-emission control transistor so that the light-emission control transistor is turned on in the saturation region for a light emitting period during which the light emitting element is allowed to emit light.
