Abstract
A pixel includes an organic light-emitting diode; a first transistor that receives a signal in response to a voltage applied to a first node and controls an amount of current flowing from a second node electrically connected to a power supply voltage line to the organic light-emitting diode; a fourth transistor electrically connected between the first node and a first initializing voltage line; and a bias capacitor electrically connected between the second node and a light-emission control line, the bias capacitor including a first capacitor electrode and a second capacitor electrode. The first capacitor electrode of the bias capacitor and a semiconductor layer of the first transistor are disposed on a same layer, and the second capacitor electrode of the bias capacitor and a second portion included in a gate electrode of the fourth transistor are disposed on a same layer.
