Claim Text:
1. A pixel circuit comprising: a sampling transistor having a gate electrode controlled by a first scanning line and a second electrode connected to a signal line; a driving transistor having a gate electrode connected to a third electrode of the sampling transistor, and having a source electrode and a drain electrode; a light emitting element connected between a drain electrode of the driving transistor and a first power supply line and driven by current supplied from the driving transistor; a storage capacitor connected between the gate and source electrodes of the driving transistor; a switching transistor having a gate electrode controlled by a second scanning line, a second electrode connected to the source electrode of the driving transistor, and a third electrode connected to a preset potential line; a diode-connected transistor having gate and second electrodes connected to the source electrode of the driving transistor and a third electrode connected to a first second power supply line; and a shunt transistor having a gate electrode controlled by a third scanning line, a second electrode connected to the drain of the driving transistor, and a third electrode connected to a sink potential line.
