Abstract
Official abstract text for this publication.
A color conversion panel includes a substrate and a red color conversion layer, a green color conversion layer, and a transmission layer which are disposed on the substrate. The transmission layer includes at least one of a pigment and a dye.
First claim
Opening claim text (preview).
What is claimed is: 1 . A color conversion panel comprising: a substrate; and a red color conversion layer, a green color conversion layer, and a transmission layer which are disposed over the substrate, wherein the transmission layer comprises at least one of a pigment and a dye. 2 . The color conversion panel of claim 1 , further comprising a blue blocking filter disposed between at least one of the red color conversion layer and the green color conversion layer and the substrate. 3 . The color conversion panel of claim 1 , further comprising an assistance transmission layer disposed between at least one of the red color conversion layer and the green color conversion layer and the substrate. 4 . The color conversion panel of claim 1 , further comprising a light blocking member which comprises light blocking portions, each of which is disposed between immediately neighboring two among the red color conversion layer, the green color conversion layer, and the transmission layer. 5 . A display device comprising: a display panel; and a color conversion panel disposed over the display panel, the color conversion panel comprising a substrate overlapping the display panel, and a red color conversion layer, a green color conversion layer, and a transmission layer which are disposed between the substrate and the display panel, wherein the transmission layer comprises at least one of a pigment and a dye. 6 . The display device of claim 5 , wherein the red color conversion layer and the green color conversion layer do not comprise the pigment and the dye. 7 . The display device of claim 5 , wherein at least one among the red color conversion layer, the green color conversion layer, and the transmission layer comprises scattering members. 8 . The display device of claim 7 , wherein the content of the scattering members included in the transmission layer is different from that of each or one of the red color conversion layer and the green color conversion layer. 9 . The display device of claim 5 , wherein the red color conversion layer and the green color conversion layer comprise at least one of a phosphor and a quantum dot. 10 . The display device of claim 9 , wherein the transmission layer does not comprise the phosphor and the quantum dot. 11 . The display device of claim 5 , wherein the pigment is a blue pigment, and the dye is a blue dye. 12 . The display device of claim 5 , further comprising a blue blocking filter disposed between at least one of the red color conversion layer and the green color conversion layer and the substrate. 13 . The display device of claim 5 , further comprising an assistance transmission layer disposed between at least one of the red color conversion layer and the green color conversion layer and the substrate. 14 . The display device of claim 5 , further comprising a light blocking member which comprises light blocking portions, each of which disposed between immediately neighboring two among the red color conversion layer, the green color conversion layer, and the transmission layer.
