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.

Abstract: A display apparatus includes a substrate including a display area and a peripheral area outside the display area, a display element arranged on the substrate in the display area, an encapsulation layer arranged on the display element, a first insulating layer arranged on the encapsulation layer and including a first opening that corresponds to a light-emitting area of the display element, and a second insulating layer covering the first insulating layer. A second refractive index of the second insulating layer is greater than a first refractive index of the first insulating layer, and a side surface of the first insulating layer defining the first opening includes a staircase-shaped step.
