Abstract
A pixel circuit to be connected to a data line and first and second power supply lines includes a light emitting element connected between the first power supply line and the second power supply line; a driving transistor to control a current flowing from the first power supply line to the second power supply line through the light emitting element according to a voltage of a first node; a first switching element connected between the first node and a second node; a second switching element connected between the second node and a third node; a first capacitor connected between the first power supply line and the first node; and a second capacitor connected between the second node and the data line.
