Abstract
A method for manufacturing a wavelength converting film is provided. A release film is provided. At a least one coating process is performed to form at least one wavelength converting layer on the release film, wherein a first contact surface of the at least one wavelength converting layer and the release film has a first roughness. An adhesive layer is formed on a surface of the wavelength converting layer farthest from the release film, wherein a second contact surface of the adhesive layer and the wavelength converting layer has a second roughness. The second roughness is greater than the first roughness.
