    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: A polarizing plate and a liquid crystal display using the same are disclosed. The polarizing plate includes a polarizer made of a synthetic resin and protective films. The same protective films are attached to both sides of the polarizer. When a FTIR-ATR method is carried out with respect to the both sides of the protective film and a peak intensity (A) in the wavelength range around 1488 cm−1 of one side, a peak intensity (B) in the wavelength range around 1365 cm−1 of one side, a peak intensity (A′) in the wavelength range around 1488 cm−1 of another side and a peak intensity (B′) in the wavelength range around 1365 cm−1 of another side are measured, and (C) and (C′) are represented by the relationships: (A)/(B)=(C) and (A′)/(B′)=(C′), (C)/(C′)≧1.2 is satisfied. The same sides of the protective films having the (C) and (C′) are adhered to both sides of the polarizer. In the polarizing plates, in accordance with the invention, even at the exposure to heat and humidity, advantageously occurrence of curling (warping) is reproduced.
