摘要： A method for manufacturing a polarizing plate in which a transparent protective film is provided on at least one surface of a polarizer with an adhesive layer interposed therebetween, wherein an adhesive is coated on a surface of the transparent protective film on which the adhesive layer is formed or/and a surface of the polarizer on which the adhesive layer is formed to form the adhesive layers, and thereafter, an aqueous liquid is caused to be present on an adhering surface when the transparent protective film and the polarizer are continuously adhered to each other with the adhesive layer interposed therebetween. A polarizing plate having uniform polarization characteristics, and excellent in durability is obtained by the method.

摘要： A polarizing film is provided that prevents display unevenness and can form a liquid crystal display and an electroluminescence display that exhibit excellent display characteristics. The polarizing film is produced in the following manner. That is, a hydrophilic polymer film is conveyed by means of a guide roll so as to be impregnated in an aqueous solvent in a swelling bath and is allowed to swell. In this swelling step, at least a first guide roll is arranged in the swelling bath, and when the polymer film is impregnated in and allowed to travel in the aqueous solvent, the polymer film is brought into contact with the first guide roll within a time up to when swelling reaches a saturation state. Further, the polymer film is dyed using a dichroic substance and stretched.

摘要： An end face of a polarization plate 10 cut by laser according to the present invention becomes a substantially flat surface having only sloping micro waviness 16 because of having been melted once to be solidified. Since the surface has few stress-concentrated part that may cause microcracks, this prevents microcracks from easily being produced.
