Abstract
One embodiment of the present invention is a color filter structure for converting the wavelength of light emitted from a light-emitting element, comprising a light conversion layer comprising a first resin and quantum dots having a core / shell structure dispersed within the first resin, and a light absorption layer stacked on the light conversion layer. The light absorption layer comprises a second resin and semiconductor nanoparticles dispersed within the second resin that absorb light emitted from the light-emitting element. Accordingly, the color filter structure according to the present invention can improve the color purity and brightness of the emitted light.
