Abstract: An organic light-emitting device having high efficiency and long lifespan including: a first electrode; a second electrode facing the first electrode; and an organic layer between the first electrode and the second electrode and including an emission layer, wherein the organic layer includes a first compound represented by Formula 1 and a second compound represented by Formula 2: When compounds represented by Formulae 1 and 2 are included in the emission layer, organic light-emitting devices may exhibit improved driving voltage, improved luminance, improved efficiency, and/or improved lifespans.

Abstract: A display apparatus includes, a light emitting device disposed over an emission area of a substrate and emitting light of a first wavelength, and a display panel including a color filter disposed over the light emitting device, a transmittance of the color filter of light of the first wavelength is less than a transmittance of the color filter of light of a second wavelength and the second wavelength is greater than the first wavelength, and an angle-dependent color change of the display panel in the emission area of the substrate at standard coordinates (0.1754, 0.1579) is within a trajectory range of about 10 of a MacAdams ellipse.
