A light emitting display apparatus includes a pixel including a pixel driving circuit and a light emitting device, and a gate driver supplying gate signals to the pixel driving circuit. The pixel driving circuit includes a switching transistor, a driving transistor, and a first light emitting transistor. The first light emitting transistor is connected between an anode of the light emitting device and a first node, the driving transistor controls the size of the current supplied to the light emitting device through the first node and the first light emitting transistor, and the switching transistor controls the supply of a data voltage to the light emitting device through the first node. During the use of the light emitting display apparatus, one second is divided into a refresh period and an anode reset period, and the switching transistor is turned on only during the refresh period.
