Abstract

An organic light-emitting display apparatus includes an organic light-emitting diode, a switching transistor, a first light emission control transistor, and a driving transistor. The organic light-emitting diode includes an anode and a cathode for receiving a reference voltage. The switching transistor includes a gate electrode for receiving an nth scan signal and a source electrode for receiving a data signal, and is an NMOS transistor. The first light emission control transistor includes a gate electrode for receiving a light emission control signal, and is configured to turn on upon receiving the light emission control signal to determine a timing of flow of a driving current to the organic light-emitting diode, and is a PMOS transistor. The driving transistor is connected to the switching transistor and the first light emission control transistor and provides the driving current to the organic light-emitting diode.
