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 light filter layer;
• a first light shielding layer defining a plurality of openings, wherein the first light filter layer is disposed in one of 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 a plurality of another openings;
• a plurality of light emitting diodes disposed in the another plurality of another openings;
• and
• a material layer disposed between the first light shielding layer and the second light shielding layer,
• wherein in a direction parallel to an upper surface of the substrate, the second light shielding layer overlaps the plurality of light emitting diodes,
• wherein the material layer overlaps with at least two of the plurality of light emitting diodes, and the material layer comprises silicon oxide material or oxygen-containing material.
