Beschreibung
Zusammenfassung:	A display device according to an exemplary embodiment includes: a thin film transistor array panel (100); and a color conversion display panel (30) overlapping the thin film transistor array panel, the color conversion display panel including: a substrate (310); a color conversion layer (330R, 330G) positioned between the substrate and the thin film transistor array panel and including a semiconductor nanocrystal (331R, 331G); a transparent layer (330B) positioned between the substrate and the thin film transistor array panel; and at least one of a first buffer layer (327) positioned between the color conversion layer and the substrate and between the transparent layer and the substrate, and a second buffer layer (347) positioned between the color conversion layer and the thin film transistor array panel and between the transparent layer and the thin film transistor array panel, wherein the first buffer layer and/or second buffer layer have a lower refractive index than a refractive index of the color conversion layer and the transparent layer, so that total internal reflection of light is generated at the respective interfaces between the color conversion layer and the first and/or second buffer layers.
