Abstract
A pixel in a display device includes a light emitting element, a first transistor for controlling an amount of current flowing from a first power source to a second power source via the light emitting element corresponding to a voltage applied to a first node, and second and third transistors coupled in series between a holding power source and a second node coupled to one electrode of the first transistor, wherein the second transistor includes a gate electrode coupled to an emission control line, and wherein the third transistor includes a gate electrode coupled to a scan line.
