The invention provides an optical film with a protective film. The optical film (100) with protective film includes: an optical film (10), which has an antifouling layer (4) on the outermost surface; and a surface protective film (70), which is temporarily attached to the anti-fouling layer of the optical film. The water contact angle of the antifouling layer is above 100 degrees. The protective film has an adhesive layer (8) on the film substrate (7). The adhesion between the antifouling layer of the optical film and the adhesive layer of the surface protection film is less than 0.07N / 50mm.The thickness of the adhesive layer is preferably 16 [mu]m or more.
