US Patent No: 9057842
Polarizing plate, method of manufacturing the same and liquid crystal display employing the same
Abstract
Disclosed are a polarizing plate manufacturable by a manufacturing method safe in work and less imposing a burden on the environment using protective films excellent in adhesion with the polarizer and a method for manufacturing the same. A liquid crystal display device using the polarizing plate and having both a large viewing angle and a high visibility (high contrast and so forth) is also disclosed. The polarizing plate made by holding both surfaces of the polarizer held with protective films is characterized in that at least one protective film is a protective film hydrophilized by either a plasma treatment or a corona treatment and that the surface energy of the protective films before the hydrophilization and the surface energy of the protective films after the hydrophilization satisfy a predetermined relational expression.
