Abstract: A display device includes first and second pixels disposed adjacent to each other. Each of the first and second pixels includes a light-emitting element, a first transistor controlling a driving current flowing in the light-emitting element, a second transistor supplying a data voltage to a first electrode of the first transistor, a third transistor electrically connecting a second electrode of the first transistor and a gate electrode of the first transistor, and a fourth transistor discharging the gate electrode of the first transistor with a first initialization voltage. The first and second pixels share a fourth-first transistor including a first electrode connected to the fourth transistor of the first pixel and the fourth transistor of the second pixel, and a second electrode connected to a first initialization voltage line supplying the first initialization voltage.
