Claim 21:
22. A display apparatus, comprising:
a substrate including a plurality of pixel areas;
a plurality of first electrodes on the plurality of pixel areas of the substrate, respectively;
a second electrode on the first electrodes;
a plurality of main light emitting layers between the first electrodes and the second electrode;
a plurality of sub light emitting layers on the second electrode to correspond to the plurality of main light emitting layers, respectively; and
a sealing layer on the plurality of main light emitting layers,
wherein the plurality of main light emitting layers comprises a material to emit a first light having a first wavelength, and
wherein the plurality of the sub light emitting layers comprise:
a first one of the plurality of sub light emitting layers comprising a material to absorb a portion of the first light and to emit a second light having a second wavelength different from the first wavelength;
a second one of the plurality of sub light emitting layers comprising a material to absorb a portion of the first light and to emit a third light having a third wavelength different from the first wavelength and the second wavelength; and
a third one of the plurality of sub light emitting layers comprising a material to absorb a portion of the first light and to emit a fourth light having the first wavelength.
