Abstract

A display apparatus includes: an organic light emitting diode (OLED) structure including in which at least one blue light-emitting unit and at least one green light-emitting unit are stacked to provide incident light in which the blue incident light and the green incident light are mixed; a first pixel, a second pixel, and a third pixel disposed on the OLED structure; color conversion layers disposed on at least two of the first, the second, or the third pixels, and including quantum dots for converting the mixed incident from the OLED structure into light of a predetermined color; and first, second, and third color filters disposed on the first, the second, and the third pixels, respectively, to absorb or block light of a predetermined wavelength band, wherein a conversion value of an area of a spectrum in a wavelength region of 380 nanometers to 780 nanometers of the green incident light with respect to a difference between a wavelength at the maximum transmittance of the second color filter and the medial wavelength of the incident green light (Δλ) may be 3.6 or greater and 13 or less.
