Abstract: A display device includes: a display panel including a first light emitting area to emit a source light; a barrier wall on the display panel, and having a first opening corresponding to the first light emitting area; a first light control pattern in the first opening; and a light shielding pattern between the display panel and the barrier wall, and overlapping with the barrier wall and the first opening. The light shielding pattern overlaps with a portion of the first light control pattern.

Abstract: A display device including a base layer including first to third pixel regions and a peripheral region, light emission elements, and a color filter layer. The color filter layer includes a first color filter overlapping the first pixel region and the peripheral region, and including first and second openings, a second color filter overlapping the second pixel region and the peripheral region, and including third and fourth openings, and a third color filter overlapping the third pixel region and the peripheral region, and including fifth and sixth openings. The peripheral region includes a single-layered region not overlapped by the first and second color filters and overlapped by the third color filter and a multi-layered region overlapped by at least two of the first and third color filters. The single-layered region is disposed on an outer side of each of the first to fourth openings in a plan view.

Abstract: A display device includes a first substrate, a pixel structure, a first optical filter, a first-color filter, a second optical filter, a second-color filter, and a second substrate. The pixel structure is disposed between the first substrate and each of the optical filters. The first-color filter is disposed on the first optical filter and has a first refractive index. The second optical filter is spaced from the first optical filter and includes a second-color pigment. The second-color filter is disposed on the second optical filter and has a second refractive index. The second substrate is disposed on the first color filter and the second color filter and has a third refractive index. A difference between the third refractive index and the second refractive index is less than a difference between the third refractive index and the first refractive index.

Abstract: A display panel includes light emitting elements which generate source light, pixel regions from which light is emitted, a layer including light control patterns, and a layer including light shielding patterns which are in each of the pixel regions and are spaced apart from each other within a respective pixel region, where the light shielding patterns each includes a first light shielding pattern including a light shielding material, and a second light shielding pattern which corresponds to the first light shielding pattern, includes a metal material and is closer to the layer including the light control patterns than the first light shielding pattern.
