摘要： A polarizing plate produced according to the present invention includes a polarizing film and a protective layer bonded to a surface of the polarizing film, where the protective layer has no irregularities like record grooves caused by stretching of the polarizing film, so that the polarizing plate with an improved appearance provides clear images even when reflected light is applied. Such a polarizing plate is produced by laminating a protective layer on at least one surface of a polarizer while limiting moisture content of the polarizer to a range from 5% to 30%. A value for the moisture content is obtained by a calculation based on an equation of moisture content (%)=[(A−B)/B]×100, when A denotes weight of the polarizer before bonding and B denotes weight of the polarizer after being kept in a dryer of 120° C. for seven hours.

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.
