Disclosed is a brightness enhancing film, including a multilayered thin film wherein a plurality of first thin film layers which are optically anisotropic and a plurality of second thin film layers which are optically isotropic are alternately stacked, the multilayered thin film including a first wavelength reflection region which reflects a wavelength of 160 ~ 451 nm, a second wavelength reflection region which reflects a wavelength of 451 ~ 836 nm, and a third wavelength reflection region which reflects a wavelength of 836 ~ 1040 nm, and a thickness of each of the first and second thin film layers in the first and second wavelength reflection regions is linearly increased from the short wavelength reflection side toward the long wavelength reflection side, and a thickness of each of the first and second thin film layers in the third wavelength reflection region is nonlinearly increased from the short wavelength reflection side toward the long wavelength reflection side. |
