PROBLEM TO BE SOLVED: To certainly laminate a sheet material without wrinkles on a flat surface. SOLUTION: A laminator 1 is constituted so that a linear polarization separation sheet 3 and a linear polarization film 5 are respectively drawn out of a raw linear polarization separation sheet roll 2 and a raw linear polarization film roll 4 and laminated while pressed by a laminating roll 6. The draw-out direction 2a from the raw linear polarization separation sheet roll 2 is biased so as to be inclined by about 1°with respect to the parallel line 6d of the rotary shaft of the laminating roll 6. If the angular shift of a transmission axis 3a with a transmission axis 5a is about±4°, optical characteristics are not almost affected. When the sheet 3 and the film 5 are laminated by biasing the draw-out direction of the raw roll 2, both of them are flatly laminated to prevent the occurrence of undulating wrinkles.
