Display device and method of manufacturing the display device
A display device includes a first pixel, a second pixel, and a third pixel, bank patterns disposed on a substrate, light-emitting elements disposed between the bank patterns, color conversion layers disposed on the light-emitting elements between the bank patterns, and protective layers disposed on the color conversion layers, wherein the protective layers in the first pixel, the second pixel, and the third pixel have different thicknesses.
1 . A display device comprising:
a first pixel;
a second pixel;
a third pixel;
bank patterns disposed on a substrate;
light-emitting elements disposed between the bank patterns;
color conversion layers disposed on the light-emitting elements between the bank patterns;
protective layers disposed on the color conversion layers; and
a first color filter disposed in the first pixel,
wherein the protective layers in the first pixel, the second pixel, and the third pixel have different thicknesses,
wherein the protective layers include a first protective layer on the color conversion layers and a second protective layer on the first protective layer, and
wherein the first color filter is disposed between the first protective layer and the second protective layer.
2 . The display device of claim 1 , wherein a thickness of the protective layers in the third pixel is greater than at least one of a thickness of the protective layers in the first pixel and a thickness of the protective layers in the second pixel.
3 . The display device of claim 2 , wherein the thickness of the protective layers in the first pixel is greater than the thickness of the protective layers in the second pixel.
4 . The display device of claim 1 , wherein the first protective layer is disposed in the third pixel and includes openings exposing the first pixel and the second pixel.
5 . The display device of claim 1 , wherein the second protective layer is disposed in the first pixel and the third pixel and includes an opening exposing the second pixel.
6 . The display device of claim 1 ,
wherein the first color filter is disposed between the color conversion layers and the second protective layer.
7 . The display device of claim 1 , wherein the protective layers further include a third protective layer disposed in the first pixel, the second pixel, and the third pixel.
8 . The display device of claim 1 , further comprising:
a second color filter disposed in the second pixel,
wherein the second color filter is disposed between the color conversion layers and the third protective layer.
9 . The display device of claim 8 , wherein
the first pixel is a first color pixel,
the second pixel is a second color pixel,
the third pixel is a third color pixel, and
the light-emitting elements emit a third color.
10 . The display device claim 9 , wherein the color conversion layers includes:
a first color conversion layer disposed in the first pixel;
a second color conversion layer disposed in the second pixel; and
a scattering layer disposed in the third pixel.
