Abstract: A display device includes a display panel, a first refractive pattern disposed on the display panel, where the first refractive pattern has a first refractive index, has a planar shape including a center portion and a peripheral portion, and defines a plurality of refractive openings in which a first refractive opening whose peripheral portion extends from a side of the center portion and a second refractive opening whose peripheral portion extends from a vertex of the center portion are alternately arranged, and a second refractive layer disposed on the first refractive pattern, where the second refractive layer has a second refractive index less than the first refractive index.

Abstract: A display device includes a display layer including an active area including a plurality of pixel areas, and a peripheral area adjacent to the active area, an insulating layer disposed on the display layer, the insulating layer including at least one first opening overlapping the plurality of pixel areas, and at least one second opening in the peripheral area, a refractive index layer disposed on the insulating layer, having a refractive index greater than a refractive index of the insulating layer, and spaced apart from the at least one second opening, and a polarizing layer overlapping the refractive index layer. At least a portion of the polarizing layer overlaps the at least one second opening.
