Abstract
Official abstract text for this publication.
A color-converting substrate includes a color-converting part including a wavelength-converting particle configured to change a wavelength of an incident light to emit a light having a color different from the incident light, a color filter pattern filtering the light emitted from the color-converting part, and a light-reflective layer disposed between the color-converting part and the color filter pattern to selectively reflect a light having a wavelength same as the wavelength of the incident light.
First claim
Opening claim text (preview).
What is claimed is: 1. A color-converting substrate comprising: a color-converting part including a wavelength-converting particle configured to change a wavelength of an incident light to emit a light having a color different from the incident light; a color filter pattern filtering the light emitted from the color-converting part; and a light-reflective layer disposed between the color-converting part and the color filter pattern to selectively reflect a light having a wavelength same as the wavelength of the incident light. 2. The color-converting substrate of claim 1 , wherein the light-reflective layer covers a light-exiting surface and a side surface of the color-converting part. 3. The color-converting substrate of claim 1 , wherein the light-reflective layer has a stacked structure including a plurality of layers having different refractive indexes. 4. The color-converting substrate of claim 1 , wherein the light-reflective layer includes a wire-grid pattern. 5. The color-converting substrate of claim 1 , wherein the light-reflective layer includes a nano-particle including silver. 6. The color-converting substrate of claim 5 , wherein the nano-particle includes an oxide core and a metal shell including silver. 7. The color-converting substrate of claim 1 , further comprising a compensation part configured to transmit an incident light without changing a wavelength of the incident light, wherein the compensation part does not overlap the light-reflective layer. 8. The color-converting substrate of claim 7 , wherein the incident light is a blue light. 9. The color-converting substrate of claim 1 , wherein the wavelength-converting particle includes a quantum dot. 10. The color-converting substrate of claim 1 , wherein the color-converting part further includes a scattering particle. 11. A display device comprising: a first substrate including an array of pixels; and a second substrate combined with the first substrate, wherein the second substrate comprises: a color-converting part including a wavelength-converting particle configured to change a wavelength of an incident light to emit a light having a color different from the incident light; a color filter pattern configured to filter the light emitted from the color-converting part; and a light-reflective layer disposed between the color-converting part and the color filter pattern to selectively reflect a light having a wavelength same as the wavelength of the incident light. 12. The display device of claim 11 , wherein the light-reflective layer covers a light-exiting surface and a side surface of the color-converting part. 13. The display device of claim 11 , wherein the light-reflective layer has a stacked structure including a plurality of layers having different refractive indexes. 14. The display device of claim 11 , wherein the light-reflective layer includes a wire-grid pattern. 15. The display device of claim 11 , wherein the light-reflective layer includes a nano-particle including silver. 16. The display device of claim 11 , wherein the second substrate further includes a compensation part configured to transmit an incident light without changing a wavelength of the incident light, wherein the compensation part does not overlap the light-reflective layer. 17. A display device comprising: an array of pixels; an encapsulation layer covering the pixels; a color-converting part disposed on the encapsulation layer and including a wavelength-converting particle configured to change a wavelength of an incident light to emit a light having a color different from the incident light; a color filter pattern disposed on the color-converting part and configured to filter the light emitted from the color-converting part; and a light-reflective layer disposed between the color-converting part and the color filter pattern to selectively reflect a light having a wavelength same as the wavelength of the incident light. 18. The display device of claim 17 , wherein the light-reflective layer has a stacked structure including a plurality of layers having different refractive indexes. 19. The display device of claim 17 , wherein the light-reflective layer includes a wire-grid pattern. 20. The display device of claim 17 , wherein the light-reflective layer includes a nano-particle including silver.
