Abstract: A display apparatus includes first to third pixels, and the first pixel includes a reflective layer; a first electrode; a light emitting layer; a second electrode; and a first color filter to transmit light of the first wavelength band. The reflective layer and the second electrode define a micro-cavity in which the light of the first wavelength band resonates. The light emitting layer includes a first organic light emitting material layer which emits the light of the first wavelength band, a second organic light emitting material layer which emits the light of the second wavelength band, and a third organic light emitting material layer which emits the light of the third wavelength band.
