Abstract: A display apparatus including pixels, each including a driving transistor comprising a first terminal, a second terminal, a first gate, and a second gate electrically connected to the second terminal. Each pixel further includes a first transistor electrically connected to a driving voltage line and the first terminal of the driving transistor, a second transistor electrically connected to the second terminal of the driving transistor and a light-emitting diode, a first capacitor electrically connected to the first gate of the driving transistor and the second terminal of the driving transistor, and a second capacitor electrically connected to the driving voltage line and the second terminal of the driving transistor. A timing at which a first gate signal is applied to a gate of the first transistor and a timing at which a second gate signal is applied to a gate of the second transistor are different from each other.
