Zusammenfassung:The present disclosure provides light emitting devices (100) and display apparatuses including the same. In some embodiments, a light emitting device (100) includes a first light emitting element (110) configured to emit light of a first wavelength, a PN junction layer (120) provided on the first light emitting element (110), and a second light emitting element (130) provided on the PN junction layer (120) and configured to emit light of a second wavelength different from the first wavelength. The PN junction layer (120) includes a first conductivity type semiconductor layer (121) provided on the first light emitting element (110) and doped with impurities of a first conductivity type, and a second conductivity type semiconductor layer (122) provided on the first conductivity type semiconductor layer (121) and doped with impurities of a second conductivity type electrically opposite to the first conductivity type.
