摘要： Provided is an optical functional film in which air bubbles can be effectively prevented from forming during lamination, and preferably in which a carrier film does not tear readily. Also provided is a method for manufacturing a liquid crystal display device using this optical functional film. A belt-shaped optical functional film is used in order to cut away the optical functional film at predetermined intervals from the belt-shaped optical functional film to which a carrier film is bonded, with the carrier film remaining uncut; to subsequently turn over the carrier film by an edge-shaped member and peel away the optical functional film; and to laminate the exposed surface of the optical functional film to a sheet member while the optical functional film is being peeled away, wherein the optical functional film is characterized in that the flexural rigidity of the carrier film per unit length in the longitudinal direction is from 5.0×10 -5 N·mm 2 to 8.0×10 -2 N·mm 2 , and the longitudinal modulus in the longitudinal direction is from 3000 MPa to 5000 MPa.
