Abstract: Discussed is a color filter structure for converting a wavelength of light emitted from a light-emissive element. The color filter structure includes a light-conversion layer containing a first resin and quantum dots dispersed in the first resin, wherein each quantum dot has a core/shell structure. The color filter structure further includes a light-absorbing layer stacked on the light-conversion layer, wherein the light-absorbing layer contains a second resin and semiconductor nano-particles dispersed in the second resin. The semiconductor nano-particles absorb light emitted from the light-emissive element. Accordingly, the color filter structure improves color purity and luminance of the emitted light.
