The first transistor is connected between a power line and the light-emitting element. The second transistor is connected between a data line and the first transistor and receives a first scan signal. The third transistor is connected between the first transistor and a first node and receives a second scan signal. The fourth transistor is connected between the first node and an initialization line. The fifth transistor is connected between the first transistor and the first node and receives a fourth scan signal. The first and fourth scan signals are simultaneously activated, and a period of the second scan signal is smaller than or equal to a period of the fourth scan signal.
