Abstract: A display panel includes a substrate having an opening area, and a display area at least partially surrounding the opening area. Display elements are arranged in the display area. The display elements includes a pixel electrode, an opposite electrode, and an intermediate layer interposed therebetween. A multilayer film includes a first insulating layer between the substrate and the pixel electrode and a second insulating layer, of a different material, on the first insulating layer. A thin film encapsulation layer covers the display elements and includes at least one organic encapsulation layer and at least one inorganic encapsulation layer. The multilayer film includes a first groove disposed between the opening area and the display area. The first groove has an undercut structure in which a lower width of the first groove is greater than an upper width of the first groove.

Abstract: A thin film transistor (TFT) array substrate and organic light-emitting diode (OLED) display including the same are disclosed. In one aspect, the array substrate includes a substrate, a driving TFT formed over the substrate and including a driving gate electrode, and a storage capacitor including a first electrode electrically connected to the driving gate electrode and a second electrode formed over and insulated from the first electrode. The array substrate also includes an interlayer insulating film at least partially covering the first electrode and a driving voltage line formed over the interlayer insulating film and configured to supply a voltage to the driving TFT. The driving voltage line is formed on the same layer as the second electrode.
