Problems solved by technology
To the extent that the adhesive force between the PVA-based polarizer and the protective film is small, it will cause further problems when pasting the small pieces of the polarizer on the glass cell parts for liquid crystal display devices.

Abstract
The invention relates to a polarizing plate, which is a polarizing plate formed by respectively covering a group of protection films 1 and 5 selected from acrylic films and composed of cycloolefin films on both sides of the polyvinyl alcohol polarizer 3, partitioned with adhesive layers 2 and 4 formed after curing radical polymerization with glassivation transition temperature of -80 DEG C to 0 DEG C.
Description
technical field [0001] The present invention relates to polarizing plates used for liquid crystal display devices and the like. Background technique [0002] Liquid crystal display devices used in clocks, mobile phones, personal digital assistants (PDA: Personal Digital Assistant), monitors for notebook computers and desktop computers, DVD players, TVs, and the like have rapidly spread in the market. A liquid crystal display device is a device for visualizing a polarization state depending on the switching action of a liquid crystal, and uses polarized photons according to the display principle. In particular, in applications such as TVs, high luminance, high contrast, and wide viewing angles are increasingly required. Polarizing plates are increasingly required to have high transmittance, high degree of polarization, high color reproducibility, and the like. [0003] Polarizing films used in fields related to liquid crystal displays and the like are generally produced by ...
