Abstract
A pixel circuit including a light emitting element, a driving transistor, with a drain terminal thereof connected to a cathode terminal of the light emitting element, that applies a drive current to the light emitting element, a capacitor element connected to a gate terminal of the driving transistor, and a switching transistor connected between a first terminal of the capacitor element on the side of the gate terminal and a data line through which a desired program signal flows, in which the driving transistor is an inorganic oxide thin film transistor whose OFF-operation threshold voltage is a negative voltage, and a source terminal of the driving transistor and a second terminal of the capacitor element are connected to a common power source that supplies a predetermined common voltage.
