Abstract:
A display apparatus including a light emitting device layer emitting a first light having a peak wavelength of 500 nm or less, a color control layer disposed on the light emitting device layer, the color control layer including an emitting element converting the first light, a color filter layer disposed on the color control layer, and an absorptive scattering element provided in or on the color control layer. The absorptive scattering element may include a light absorbing portion, in which absorptivity of a green or red light is greater than absorptivity of the first light. Accordingly, reflectance of the display apparatus to an external light may be reduced.
