Display device

A display device, comprising:

• a substrate;
• a plurality of pixels disposed on the substrate, wherein one of the plurality of pixels comprises:
• a first color conversion layer;
• a first light filter layer disposed on the first color conversion layer;
• and
• a dielectric layer disposed between the first light filter layer and the first color conversion layer, wherein a refractive index of the dielectric layer is less than a refractive index of the first light filter layer;
• a first light shielding layer defining a plurality of openings, wherein at least one of the first color conversion layer, the dielectric layer and the first light filter layer is disposed in the plurality of openings;
• a second light shielding layer disposed on the substrate and at least partially overlapped with the first light shielding layer, and the second light shielding layer defining another plurality of openings;
• a spacer element disposed between the first light shielding layer and the second light shielding layer;
• and
• a plurality of light emitting diodes disposed in the another plurality of openings, wherein in a direction parallel to an upper surface of the substrate, the second light shielding layer overlaps the plurality of light emitting diodes.
