Abstract: The present disclosure provides a display device and a display panel. The display device includes an optical area included in a display area in which images can be displayed and allowing light to be transmitted, a normal area included in the display area and located outside of the optical area, a cathode electrode commonly disposed in the optical area and the normal area and including a plurality of cathode holes in the optical area, and a plurality of ring patterns respectively corresponding to the plurality of cathode holes. As each ring pattern is disposed to overlap an edge of each cathode hole, an optical electronic device located under the optical area is able to perform a high-performance operation. For example, when the optical electronic device is a camera, the display device enables the camera to acquire a high-quality image.
