Abstract
A display device includes a color conversion pattern including first red quantum dots, a color reinforcement pattern adjacent to the color conversion pattern and including second red quantum dots, and an emission layer disposed on the color reinforcement pattern. A concentration of the second red quantum dots in the color reinforcement pattern is less than a concentration of the first red quantum dots in the color conversion pattern.

A display device comprising:
- a color conversion pattern disposed on a substrate and including first red quantum dots;
- a color reinforcement pattern disposed on the substrate adjacent to the color conversion pattern and including second red quantum dots, a monomer, and a dispersant;
- and
- an emission layer disposed on the color reinforcement pattern,
- wherein a concentration of the second red quantum dots in the color reinforcement pattern is less than a concentration of the first red quantum dots in the color conversion pattern, and
- wherein the color reinforcement pattern and the color conversion pattern do not overlap each other in a plan view.
