Abstract: A display device includes: a base layer; and sub-pixels disposed on the base layer, the sub-pixels including first sub-pixels and second sub-pixels. The first sub-pixels may include a first sub-pixel and a first adjacent sub-pixel, the second sub-pixels may include a second sub-pixel, and the second sub-pixel may be disposed between the first sub-pixel and the first adjacent sub-pixel. The first sub-pixel may include a first color filter and a first refractive layer disposed on the first color filter. The first adjacent sub-pixel may include a first adjacent color filter disposed in the same layer as the first color filter. A refractive index difference between the first color filter and the first refractive layer may be different from a refractive index difference between the first adjacent color filter and a layer disposed directly on the first adjacent color filter.

Abstract: A light emitting display device includes a substrate, an organic layer, a conductor, an anode, and a pixel definition layer. The organic layer overlaps the substrate and has a connection opening. The conductor is positioned between the substrate and the organic layer. The anode is positioned on the organic layer and is partially positioned inside the connection opening. The pixel definition layer exposes an exposed portion of the anode. The organic layer has a halftone exposure portion and a neighboring portion. The halftone exposure portion overlaps the exposed portion of the anode and overlaps the conductor. The neighboring portion neighbors the halftone exposure portion. A face of the halftone exposure portion and a face of the neighboring portion are spaced from the substrate by a first distance and a second distance, respectively. A difference between the first distance and the second distance is 30 nm or less.
