Abstract: A display device including a substrate; a first electrode on the substrate; a partitioning wall on the first electrode that includes a first opening that overlaps the first electrode; a touch detection electrode on the partitioning wall; a low refractive layer on the partitioning wall and the touch detection electrode, the low refractive layer including a second opening that overlaps the first opening; and a high refractive layer on the low refractive layer. Planar shapes of the first opening and the second opening are polygons, each including a series of sides, and a distance between one side of the first opening and the second opening is different than another side of the first opening and the second opening in a plan view.

Abstract: A display device includes a first substrate and a second substrate, which face each other, and each of which includes a display area and a non-display area disposed outside the display area, a first light-blocking layer disposed in the non-display area, and a dummy color layer, in which a boundary dividing the display area and the non-display area is defined, and which is disposed in the non-display area of the first substrate to be adjacent to the boundary, where the dummy color layer includes a section in which a distribution density of the dummy color layer is decreased from the boundary to the outside of the non-display area.

Abstract: A display device includes a substrate, a pixel electrode disposed on the substrate, a bank layer which is disposed on the pixel electrode and in which a pixel opening overlapping the pixel electrode is defined, an encapsulation layer disposed on the pixel electrode and the bank layer, a sensing electrode disposed on the encapsulation layer, a first insulating layer which is disposed on the sensing electrode and in which an opening overlapping the pixel opening is defined, and a second insulating layer disposed on the first insulating layer and having a higher refractive index than a refractive index of the first insulating layer. The opening of the first insulating layer includes a first edge and a second edge separated from an edge of the pixel opening and extending in different directions from each other and a first extension part disposed at a portion where the first edge and the second edge meet.
