Abstract
A color conversion panel includes a substrate, a first color conversion layer and a second color conversion layer disposed on the substrate, a planarization layer covering the first color conversion layer and the second color conversion layer, and a polarization layer disposed on the planarization layer. An outlet from the planarization layer penetrates the polarization layer.
