Abstract
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.
Claims18
A color conversion panel, comprising:
- a substrate having a first surface and a second surface opposite to the first surface;
