Abstract

A pixel includes a light-emitting device, a driving TFT for controlling a magnitude of a current from a power line to the light-emitting device according to a gate-source voltage, a storage capacitor disposed between the power line and a gate of the driving TFT, a scan TFT to transfer a data voltage to a source of the driving TFT in response to a first signal, first and second compensation TFTs serially connected between a drain and the gate of the driving TFT, a gate initialization TFT to apply a first voltage to the gate of the driving TFT in response to a second signal, an anode initialization TFT to apply a second voltage to an anode of the light-emitting device in response to a third signal, and a shield capacitor disposed between a node between the first and second compensation TFTs and the power line or a second voltage line.
