PROBLEM TO BE SOLVED: To easily laminate each optical film in a proper direction without any reversal, when laminating a plurality of optical films having an optical axis. SOLUTION: The optical film 22 is provided, which has a specific optical axis arranged in between the liquid crystal display element and a light source. Positioning marks 22a, 22b having the same shape and size are formed at symmetrically at positions of the intersecting point of the horizontal and vertical center lines CL1, CL2 of the optical film 22 with a center as a point O on two opposed sides 221, 222 of the optical film 22.
