Abstract: A method of manufacturing a display device is disclosed. In one aspect, the method includes forming an active layer over a substrate, forming a first insulating layer over the active layer, forming a gate electrode over the active layer, and forming an alignment mark over the substrate. The forming of the alignment mark includes forming a first layer including a first pattern and forming a second layer over the first layer and including concave and convex portions formed along the first pattern. The first insulating layer is interposed between the first and second layers.

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.
