Abstract
An electro-optical apparatus is provided with an active-matrix drive circuit that applies a voltage based on an image signal tone to a light-emitting element, and includes: a first transistor for driving, a source of the first transistor being connected to an anode of the light-emitting element; a second transistor for setting an anode voltage, the second transistor being connected between the anode and a power source, and determining a voltage applied to the anode; and a holding capacitor and a third transistor connected to the anode for holding the anode voltage during a light-emission period.
