Abstract: A display device includes pixels, and first, second, and third gate lines and data lines connected to the pixels. At least one of the pixels includes a light emitting element, a first transistor connected between a first power source and the light emitting element for driving the light emitting element according to a voltage of a first node, a second transistor connected between the first node and a corresponding data line, and driven according to a voltage of a corresponding first gate line, a capacitor connected between the first node and a second node between the first transistor and the light emitting element, a third transistor between the second node and an initialization power line, and driven according to a voltage of a corresponding second gate line, and a fourth transistor connected between the first and second nodes, and driven according to a voltage of a corresponding third gate line.
