Abstract: The present invention provides a polarizer and a polarizing plate having less dimensional changes to heat stress. The present invention provides also a liquid crystal display that includes the polarizer and the polarizing plate, and is free of color irregularity or decoloration. The polarizer has shrinkage force of not more than 4.0 N/cm in the absorption axis direction after being heated at 80° C. for 30 minutes. A protective film is laminated on at least one surface of the polarizer in order to form a polarizing plate, and the polarizing plate has a following relationship of 0.01?A/B?0.16 when A denotes a thickness of the polarizer and B denotes a thickness of the protective film.

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.

Abstract: A polyvinyl alcohol-based polarizing film is provided, and the polarizing film has excellent surface smoothness while the light transmittance and the polarization degree are improved due to the high stretch ratio. The polarizing film is obtained from a polyvinyl alcohol film having a thickness ranging from 85 ?m to 150 ?m by dyeing the film with a dichroic substance and stretching it to 4-7 times its original length.

The transparent protective layer can be subject to a pre-treatment selected from a hard-coat treatment and an anti-glare treatment.
