Abstract
A pixel includes a light emitting device, a first transistor for controlling an amount of current flowing from a first power source to a second power source via the light emitting device, in response to a voltage applied to a first node, a second transistor coupled between a data line and a second node corresponding to a first electrode of the first transistor, and including a gate electrode coupled to a first scan line, a third transistor coupled between the first node and a third node corresponding to a second electrode of the first transistor, and including a gate electrode coupled to the first scan line, and a fourth transistor coupled between the third transistor and the third node, and configured to maintain a turn-on state.
