Abstract: An organic light-emitting diode display includes an organic light-emitting display device including a first electrode, an intermediate layer including an organic emission layer, and a second electrode; a first inorganic encapsulation layer on the second electrode; a second inorganic encapsulation layer on the first inorganic encapsulation layer; and an organic encapsulation layer on the second inorganic encapsulation layer. A refractive index of the first inorganic encapsulation layer is higher than a refractive index of the second inorganic encapsulation layer. The first inorganic encapsulation layer has an extinction coefficient of 0.02 to 0.07 and a refractive index of 2.1 to 2.3 at a blue wavelength.

Abstract: A display panel includes a substrate comprising an opening. A plurality of light-emitting diodes is arranged in a display area surrounding the opening. A plurality of grooves is located in a middle area between the opening and the display area and disposed on at least one inorganic insulating layer on the substrate. At least one groove of the plurality of grooves includes a tip protruding towards a center of the at least one groove. The tip includes a transparent layer and a metal pattern layer disposed on the transparent layer. The metal pattern layer includes a groove portion corresponding to an edge of the tip. The groove portion exposes at least a portion of an upper surface of the transparent layer.

Abstract: A foldable display device includes a display panel having a bent display portion and a non-bent display portion, and a touch sensing unit provided on the display panel and including a bent touch portion and a non-bent touch portion. The touch sensing unit includes a plurality of sensing electrodes, and each of the sensing electrodes comprises a conductive material having a porous structure. The porous structure resists cracking and the resulting sensing electrodes may have an optical anisotropy. Thus, the sensing electrodes may perform a polarizing function to eliminate need for a separate polarizer.
