Abstract
When performing gradation expression using a time division driving method, an operational frequency of a driving circuit is suppressed, and non-light emitting time is eliminated to increase the light emitting time. Each of a number of pixel circuits includes a light emitting element, a driver element for turning on or off a driving current of the light emitting element, a switching element for controlling connection of a gate electrode of the driver element with a signal line, and a capacitance to which a signal voltage supplied from the signal line to the gate electrode of the driver element is written.
