Display device, electronic device including the same, and method of manufacturing the display device

A method of manufacturing a display device, the method comprising:

• forming, on a substrate, a display layer comprising a light-emitting diode and a bank layer that comprises a lower opening defining an emission area of the light-emitting diode;
• forming, on the display layer, a light-shielding layer comprising an upper opening at least partially aligned the lower opening;
• forming, within the upper opening, a preliminary color filter layer comprising a color filter material, a plurality of scattering particles, and a base resin;
• and
• forming a color filter layer through a pre-baking process of heating the preliminary color filter layer.

An electronic device comprising:

• a display device configured to provide an image;
• and
• a housing accommodating the display device,
• wherein the display device comprises:
• a substrate;
• a display layer disposed on the substrate and comprising a light-emitting diode and a bank layer that comprises a lower opening defining an emission area of the light-emitting diode;
• and
• an optical control layer disposed on the display layer and comprising a light-shielding layer and a color filter, the light-shielding layer comprising an upper opening at least partially aligned with the lower opening and the color filter filling the upper opening;
• wherein the color filter comprises a color filter material, a plurality of scattering particles, and a base resin, and
• the plurality of scattering particles are disposed in an upper area of the color filter.
