Polarizing plate laminated with an improved glue composition and a method of manufacturing the same

摘要

The present invention generally relates to method of forming a polarizing plate comprising providing two cover sheets each comprising a low birefringence protective polymer film and a layer promoting adhesion to poly(vinyl alcohol)-containing films that comprises a dissolved first poly(vinyl alcohol) having a degree of hydrolysis of at least 98%. A glue composition is applied when bringing the PVA dichroic polarizing film into contact with the cover sheets, the glue composition comprising a dissolved second poly(vinyl alcohol) having a degree of hydrolysis of at least 98% in combination with crosslinking agent.
