Display device and method of manufacturing the same
A display device includes a base substrate, an organic layer on the base substrate and including a pattern region having an uneven pattern formed thereon, and a non-pattern region having a substantially flat surface, a light-emitting element on the organic layer, and a color conversion pattern on the light-emitting element and overlapping the pattern region and the non-pattern region.
1. A method of manufacturing a display device, the method comprising:
forming a thin film transistor in a light-emitting region on a base substrate;
forming an organic layer on the thin film transistor, the organic layer comprising a pattern region with an uneven pattern formed thereon and overlapping the thin film transistor in a plan view, and a non-pattern region having a flat surface, the organic layer having a through-hole partially exposing the thin film transistor, wherein the pattern region and a first portion of the non-pattern region being formed in the light-emitting region;
forming a light-emitting element on the organic layer;
forming an encapsulation layer on the light emitting element, the encapsulation layer including an inorganic encapsulation layer and an organic encapsulation layer, each of the inorganic and organic encapsulation layers having an uneven surface corresponding to the uneven pattern of the organic layer; and
forming a color conversion pattern on the encapsulation layer to overlap the pattern region and the first portion of the non-pattern region in the light-emitting region.
2. The method of claim 1 , wherein the formation of the organic layer comprises:
providing an organic material comprising a positive photosensitive material on the thin film transistor; and
concurrently forming the through-hole and the uneven pattern, using one mask,
wherein the uneven pattern is a recess pattern, and a width on a plane of the recess pattern is about 2.5 μm or less.
3. The method of claim 1 , wherein the formation of the organic layer comprises:
forming a first organic layer having a substantially flat surface on the thin film transistor; and
forming a second organic layer comprising a negative photosensitive material and having the uneven pattern on the first organic layer,
wherein the uneven pattern comprises a convex pattern.
4. The method of claim 1 , wherein:
a second portion of the non-pattern region is formed in a non-light-emitting region of the display device.
