PROBLEM TO BE SOLVED: To provide an obliquely stretched film having an excellent mechanical property with the rupture in the direction of the stretching axis being suppressed, even for the case where a relatively hard and brittle resin such as an acrylic resin is included.SOLUTION: An obliquely stretched film is produced by having: the at least one edge portion with respect to the one direction selected from the width direction and the longitudinal direction, and the portion other than said edge portion composed of thermoplastic resins which are different from each other; the folding endurance exhibited by the thermoplastic resin composing the edge portion being higher compared to the thermoplastic resin composing the portion other than the edge portion; and the stretching axis inclined with respect to the width direction and the longitudinal direction. |
