Display device

A display device comprising:

• a first pixel region, a second pixel region, and a third pixel region that are adjacent to each other in a plan view;
• a display panel comprising a first light emitting element overlapping with the first pixel region, a second light emitting element overlapping with the second pixel region, and a third light emitting element overlapping with the third pixel region;
• and
• a refractive index control layer comprising a first refractive index control part corresponding to the first light emitting element, and a second refractive index control part corresponding to the second light emitting element,
• wherein the first refractive index control part and the second refractive index control part have different thicknesses from each other.
