Zusammenfassung:Each of pixel circuits is controlled by at least a first scanning signal and a second scanning signal. A first scanning circuit supplies the first scanning signal to first scanning lines. A second scanning circuit supplies the second scanning signal to second scanning lines. The first scanning signal is a scanning signal that turns ON/OFF an n-type transistor in a pixel circuit for refresh operation including writing a data voltage to the pixel circuit. The second scanning signal is a scanning signal that controls whether to supply lighting current to a light-emitting element in the pixel circuit. An output of a clamp switching circuit is connected to a first scanning signal line. The clamp switching circuit is controlled by the second scanning signal to keep the first scanning signal line at a low-level potential for at least a part of an emission period.
