Abstract: A display panel that includes a plurality of pixels, each pixel includes a first area including a display device; a second area including a first reflective member to reflect light received from the display device to an outside of the display panel for viewing, and a third area including a second reflective member reflecting external light to provide a mirror function when the display device is not displaying an image. The display device includes a pair of reflective electrodes to cause the light produced by the display device to propagate towards the second area. One of the two electrodes may further include a transparent conductive material to provide a waveguide function to the display device in the first area to improve coupling efficiency of the display panel.
