Abstract

A display device including a light source including a first electrode (112) having a light reflectance for a first light of greater than or equal to about 60 %; an organic light emitting layer (120a) disposed on the first electrode and emitting the first light; and a second electrode (114) disposed on the organic light emitting layer and having a light transmittance in a visible wavelength region of greater than or equal to about 70 %, wherein the light source has a first absorption peak in a wavelength region of about 650 nanometers (nm) to about 750 nm or a second absorption peak in a wavelength region of about 550 nm to about 600 nm at a viewing angle of about 55 degrees to about 85 degrees, and a color filter layer (130r, 130g, 130b) disposed above the light source and including a quantum dot configured to convert the first light into a second light.
