Abstract:
A display apparatus includes pixels two-dimensionally arranged. Each of the pixels includes a light-emitting element, a capacitor which retains a voltage of a data signal, a drive transistor which feeds a current according to the voltage of the data signal to the light-emitting element, a first write transistor connected between a data signal line and a gate electrode of the drive transistor, a second write transistor connected between the first write transistor and a gate electrode of the drive transistor, and a counter transistor including a source electrode and a drain electrode, one of the source electrode and the drain electrode being connected between the first write transistor and the second write transistor. The other of the source electrode and the drain electrode of the counter transistor is connected to a counter voltage line which feeds a counter voltage.
