TECHNICAL FIELD

The present disclosure relates to a display device and, more specifically, to a color conversion display panel and a display device including the same.

DISCUSSION OF THE RELATED ART

A liquid crystal display device may include two field generating electrodes, a liquid crystal layer, a color filter, and a polarization layer. Light emitted from a light source reaches a viewer through the liquid crystal layer, the color filter, and the polarization layer. Light loss may occur in the polarizing layer, the color filter, or the other various layers of the display device. Similarly, light loss may occur in other forms of display devices such as an organic light emitting diode display.

Some forms of display devices include a color conversion display panel. Color conversion display panels may use semiconductor nanocrystals, such as quantum dots, to provide the display device with high color reproducibility and reduced light loss generated in a polarization layer or a color filter.

SUMMARY

A color conversion display panel includes a substrate. A color conversion portion is disposed on the substrate. The color conversion portion includes a semiconductor nanocrystal. A transmission portion is disposed on the substrate. A blue light blocking filter is disposed between the substrate and the color conversion portion. The blue light blocking filter includes a first convex portion that protrudes toward the substrate. The transmission portion includes a first region including a scatterer and a second region including a second convex portion that protrudes toward the substrate.
