Abstract
An exemplary display device includes: a display panel; a color conversion panel overlapping the display panel; and an optical bonding layer positioned between the display panel and the color conversion panel. The color conversion panel includes: a substrate; a color conversion layer and a transmission layer positioned between the substrate and the display panel; a first capping layer having one side facing the color conversion layer and the transmission layer, and another side facing the display panel; a second capping layer positioned between the first capping layer and the display panel; and an optical layer positioned between the first capping layer and the second capping layer and/or between the second capping layer and the optical bonding layer. A refractive index of the optical layer is lower than at least one of a refractive index of the first capping layer and a refractive index of the second capping layer.
