Abstract

A color conversion panel includes a substrate. A first color conversion layer, a second color conversion layer, and a transmission layer are provided on the substrate. A first scatterer layer is provided between the first color conversion layer and the second color conversion layer. A second scatterer layer is provided between the second color conversion layer and the transmission layer. A light filter layer is provided between the first scatterer layer and the first color conversion layer, between the first scatterer layer and the second color conversion layer, between the second scatterer layer and the second color conversion layer, and between the second scatterer layer and the transmission layer.

Claims (19)
