Liquid crystal display
A liquid crystal display includes: a display panel; and a color conversion layer positioned on the display panel, wherein the color conversion layer includes a scattering layer including a color conversion media layer and scatterers.
1. A liquid crystal display comprising:
a display panel;
a substrate overlapping the display panel;
a color conversion layer disposed between the display panel and the substrate,
a scattering layer positioned between the color conversion layer and the substrate and configured to scatter light passed out from the color conversion layer, and
a light assembly supplying light to the display panel and the color conversion layer,
wherein the color conversion layer includes:
a red color conversion media layer and a green color conversion media layer disposed between the display panel and the substrate, the red color conversion media layer and the green color conversion media layer each including a quantum dot (QD) and each configured to convert a wavelength of a light passed out from the display panel;
wherein light is emitted to the outside of the liquid crystal display along the color conversion layer, the scattering layer and the substrate,
the color conversion layer further includes a blue color conversion media layer or a white color conversion media layer, and
the scattering layer does not overlap at least one of the red color conversion media layer, the green color conversion media layer, the blue color conversion media layer or a white color conversion media layer.
2. The liquid crystal display of claim 1 , wherein:
the scattering layer includes scatterers and the scatterer includes at least one selected from the group consisting of TiO 2 , ZrO 2 , Al 2 O 3 , In 2 O 3 , ZnO, SnO 2 , Sb 2 O 3 and ITO.
3. The liquid crystal display of claim 1 , wherein:
the scattering layer includes scatterers such that the scattering layer has a refractive index larger than that of the color conversion media layer.
4. The liquid crystal display of claim 1 , wherein:
the scattering layer has a refractive index of about 1.6 or more.
5. The liquid crystal display of claim 1 , wherein:
the light assembly is a light emitting diode (LED) emitting a specific wavelength band including ultraviolet rays or blue light.
6. The liquid crystal display of claim 1 , wherein:
the color conversion layer further includes a light blocking member positioned between adjacent red color conversion media layers, adjacent green color conversion media layers, and adjacent blue color conversion media layers or adjacent white color conversion media layers.
7. The liquid crystal display of claim 6 , wherein:
the scattering layer is formed only between the substrate and at least any one color conversion media layer selected from the group consisting of the red color conversion media layer, the green color conversion media layer, and the blue color conversion media layer.
8. The liquid crystal display of claim 7 , wherein:
the scatterers formed below the red color conversion media layer, the green color conversion media layer, and the blue color conversion media layer, respectively, are different from each other.
9. The liquid crystal display of claim 1 , wherein:
the display panel is positioned between the light assembly and the color conversion layer, and the scattering layer of the color conversion layer contacts the display panel.
10. The liquid crystal display of claim 1 , wherein light passing through the color conversion layer without converting a wavelength of the light is scattered to the color conversion layer again by the scattering layer.
11. The liquid crystal display of claim 1 , wherein the liquid crystal display does not include a reflection wall positioned between adjacent red color conversion media layers, adjacent green color conversion media layers, and adjacent blue color conversion media layers or adjacent white color conversion media layers.
