Abstract: The present disclosure relates to a display apparatus capable of preventing blue light incident from a light source from being scattered rearward by forming a rear scattering prevention portion on a surface of a scattering particle applied to a transparent part of a quantum dot color filter. The display apparatus includes a display panel including a liquid crystal layer and a quantum dot color filter disposed above the liquid crystal layer such that an image is displayed in front, and a backlight unit configured to supply blue light to the display panel, wherein the quantum dot color filter includes a quantum dot conversion part configured to convert blue light supplied from the backlight unit into light of a different color and emit the converted light to the outside, and a transparent part configured to scatter blue light supplied from the backlight unit to the outside and including a rear scattering prevention particle to prevent rear scattering of blue light.
