Abstract: A display device includes a display panel on which gate lines, data lines and subpixels are disposed; a gate driving circuit which drives the gate lines; and a data driving circuit which drives the data lines. Each of the subpixels includes: a light emitting device; a second transistor which has a first node, a second node that is a gate node, and a third node electrically connected to the light emitting device, and drives the light emitting device; a first transistor electrically connected between the third node and the data line; a third transistor electrically connected between the first node and the second node; and a fourth transistor electrically connected between the third node and the light emitting device. The third transistor performs a turn-off operation later than the first transistor, so that a voltage applied to the third node is transmitted to the second node via the first node.

Abstract: A display device can include a light emitting element, and a pixel driving circuit connected to the light emitting element and configured to include first to fourth nodes. The pixel driving circuit can include a driving transistor connected to the first to third nodes, a plurality of switching transistors, and a storage capacitor. Among the plurality of switching transistors, the switching transistor connected to a source node of the driving transistor is controlled by a second scan signal, and is configured to apply a data voltage to the source node of the driving transistor. The second scan signal can be applied one or more times during one frame.

Abstract: Embodiments of the disclosure relate to a display device. Since the capacitor disposed in the subpixel in the area overlapping the optical element positioned on the rear surface of the substrate of the display panel is disposed using a semiconductor material, the transparency of the area may be enhanced, and the performance of the optical function performed by the optical element forward of the surface where the display panel displays images from the rear surface of the display panel may be enhanced.
