The present invention provides a kind of manufacture method of polarization plates, and it is the manufacture method of the polarization plates of transparent protective film of being fitted on the two sides of polarizer between a pair of rolls, and the method can suppress the bubble produced between polarizer and transparent protective film.In manufacture method of the two sides of polarizer across adhesive linkage the first transparent protective film of laminating and the polarization plates of the second transparent protective film; the elasticity (elastic modelling quantity × thickness (μm)) of the first transparent protective film and the second transparent protective film is different; and crimped also cross between a pair of rolls by by above-mentioned 3 films, the conveyance direction that the above-mentioned polarizer the pair of roller of input is asked and is passed through is inclined to the highly elastic film side in the middle of above-mentioned transparent protective film. |
