Abstract: A display device includes a substrate including a display area and a non-display area surrounding the display area, a light emitting structure disposed on the substrate in the display area, a thin film encapsulation layer disposed on the light emitting structure, an optical structure including a first refractive pattern and a second refractive pattern, and a partition wall disposed on the substrate in the non-display area and surrounding the second refractive pattern. The first refractive pattern is disposed on the thin film encapsulation layer, and overlaps the light emitting structure. The second refractive pattern covers the first refractive pattern, has a refractive index smaller than a refractive index of the first refractive pattern, and includes an organic material.

Abstract: A display device includes a display panel including a first area including a peripheral region and an emission region of a pixel of a first group; and a second area including a peripheral region and an emission region of a pixel of a second group; at least one insulating layer disposed on the display panel and overlapping the second area; an organic layer disposed on the at least one insulating layer and overlapping the second area; and a light blocking pattern disposed on the organic layer and overlapping the second area. A first opening corresponding to the emission region of the pixel of the second group is formed in the organic layer, and a first light blocking opening corresponding to the first opening is formed in the light blocking pattern.
