Abstract: A display apparatus may include a back light unit including a light source and a selective light absorption sheet configured to absorb light of a predetermined wavelength range among light emitted from the light source and an image forming unit configured to transmit or block light emitted from the back light unit to form an image. The selective light absorption sheet may include a selective light absorption film configured to absorb light of a predetermined wavelength range among light emitted from the light source, at least one light blocking film configured to absorb at least one of UV light and IR light, and at least one barrier film configured to block at least one of oxygen and moisture.
