Abstract: A display device includes: a substrate; a first bank including a first sub-bank and a second sub-bank spaced apart from each other on the substrate; a first electrode on the first sub-bank; a second electrode on the second sub-bank and spaced apart from the first electrode; and a light-emitting element between the first sub-bank and the second sub-bank. Each of the first and second sub-banks has a first area having a concave curved shape in a cross section and being adjacent to the light-emitting element. The first electrode has a first section extending beyond the first sub-bank toward the light-emitting element, the second electrode has a first section extending beyond the second sub-bank toward the light-emitting element, and a width of the first section of the first electrode is different from a width of the first section of the second electrode.

Abstract: A color conversion substrate for displaying a first color, a second color, and a third color may include a base substrate, a first light-blocker, a second light-blocker, a pattern layer, a first color converter, and a second color converter. The first light-blocker contacts a surface of the base substrate and may block first light of the third color. The second light-blocker contacts the surface of the base substrate and may block second light of the third color. The pattern layer is disposed on the first light-blocker and the second light-blocker and includes an optical pattern that includes protrusions. The first color converter overlaps the first light-blocker and may convert a first portion of incident light into light of the first color. The second color converter overlaps the second light-blocker and may convert a second portion of the incident light into light of the second color.
