Abstract: A display panel includes a first transistor that contains oxide, a capacitor that includes a first electrode and a second electrode, a light emitting element connected to the capacitor and the first transistor, and an additional control electrode connected to the second electrode. The first and second electrodes are disposed on different layers from each other and are coupled to a first control electrode and a first output electrode, respectively, of the first transistor, and the light emitting element includes a light emitting layer. The additional control electrode overlap the first control electrode and the first semiconductor pattern, when viewed in a plan view. The additional control electrode and the second electrode are disposed on the same layer and form a single body.
