Abstract
A display panel includes a light emitting element layer including a light emitting element that generates a first color light, a light control layer over the light emitting element layer, a color filter layer over the light control layer, and a low refractive index layer that is between the light control layer and the color filter layer and that has a thickness of about 0.2 μm to about 2.5 μm.

A display panel comprising:
- a light emitting element layer comprising a light emitting element configured to generate a first color light;
- a light control layer over the light emitting element layer, the light control layer comprising a quantum dot;
- a color filter layer over the light control layer;
- and
- a refractive index layer, having refractive index of at most about 1.4, between the light control layer and the color filter layer, the refractive index layer having a thickness of about 0.2 μm to about 2.5 μm.
