摘要： 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.

摘要： A display apparatus includes a display panel configured to display an image. A light guide plate is disposed below the display panel. The light guide plate has a light incident surface. A light source is disposed adjacent to the light incident surface of the light guide plate to generate first light. A light conversion layer is disposed between the light guide plate and the display panel to convert a wavelength band of incident light. An optical filter layer is disposed between the light guide plate and the light conversion layer to selectively transmit or reflect incident light.
