Abstract
A display panel includes a pixel including sub pixels. The pixel includes a sub pixel area in which the sub pixels are disposed and a common area. The pixel includes a light emitting diode including an anode electrode and a cathode electrode, and the anode electrode is electrically connected to a first power line to which a high potential voltage is supplied. Each of the sub pixels includes a driving element in which a source is connected to a N1 node, a gate is connected to a N2 node, and a drain is connected to a N3 node, a capacitor connected to the N2 node and a N4 node; a N1 switching circuit connected to the N1 node; a N2 switching circuit connected to the N2 node; a N3 switching circuit connected to the N3 node; and a N4 switching circuit connected to the N4 node.
