  • Patent number: 9348075
    Abstract: A method of manufacturing a polarizing plate includes fabricating a base film, dyeing the base film by using iodine, stretching the base film to form a polarizing film, firstly drying the polarizing film at a first temperature, and secondly drying the polarizing film while sequentially increasing a temperature from the first temperature to a second temperature higher than the first temperature. The polarizing plate and a liquid crystal display including the same are manufactured through the above method.
