Abstract
A plurality of display pixels PX arranged in a matrix form respectively have a driving transistor which controls an electric current amount made to flow in a self-luminescent element, in accordance with an image signal, a first switch formed of a transistor and connected between a gate and a drain of the driving transistor, and a second switch formed of a transistor and connected between the driving transistor and the self-luminescent element. A first capacitance Cs is provided between the gate and a source of the driving transistor, and a second capacitance Cx is provided between the second switch and the gate of the driving transistor.
Claims8
