Photoluminescence device and display panel including the same

A display panel including a main area, and an peripheral area surrounding the main area and defining an edge, the display panel comprising:

• a light emitting device to generate light;
• and
• a photoluminescence device disposed on the light emitting device, and the photoluminescence device comprising:
• a plurality of color conversion patterns disposing corresponding to the main area:
• a first index of refraction layer disposed on an upper surface of the plurality of color conversion patterns;
• and
• a second index of refraction layer disposed under the plurality of color conversion patterns, and the second index of refraction layer has a refractive index lower than a refractive indexes of the plurality of color conversion patterns, and
• wherein the plurality of color conversion patterns comprises:
• a first color conversion pattern including first quantum dots to convert the light of the light emitting device to have a first wavelength;
• and
• a second color conversion pattern including second quantum dots to convert the light to have a second wavelength;
• and wherein the first index of refraction layer and the second index of refraction layer contact each other at the peripheral area.
