A laminated optical film of the present invention includes: an optical film having an optically anisotropic film; and a peeling film for protection, which is peelably affixed to the surface of the optical film through an adhesive layer; and the adhesive layer has a shear stress of 22 N/cm or less, a sticker is peelably affixed to the surface of the peeling film for protection. The effect of this invention lies in that display unevenness is unlikely to occur even if the aforementioned laminated optical film is peeled off from the sticker.
