Abstract: A light emitting display apparatus includes a pixel driving circuit including a driving transistor and an anode reset capacitor connected to a gate of the driving transistor and a light emitting device configured to emit light with a current supplied through the driving transistor. An anode reset period, where a data voltage is not supplied to the driving transistor, is between refresh periods where the light emitting device emits the light with the data voltage supplied to the driving transistor, and an anode reset voltage supplied to the anode reset capacitor in the refresh period is higher than an initial voltage which is input to the gate of the driving transistor in the refresh period.
