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 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.
