Display device and method of fabricating the same

A display device comprising:

• a base layer comprising a display area;
• a plurality of pixels arranged in the display area and comprising respective emission areas;
• a light conversion layer comprising light conversion patterns on the emission areas of the pixels, and a bank between the light conversion patterns to be around side surfaces of the light conversion patterns;
• and
• a filler layer between the light conversion layer and a surface of the base layer on which the pixels are on,
• wherein the light conversion layer has a flat surface facing the pixels,
• wherein at least one of the light conversion patterns comprises microcavities disposed only on a surface thereof, wherein the light conversion patterns and the filler layer are in contact with each other,
• wherein the microcavities on the surface of the at least one of the light conversion patterns are in contact with the filler layer, and
• wherein the filler layer overlaps with a center of each of the microcavities and extends continuously along the surface.
