[PROBLEMS] To improve the adhesion technology between a polarizing film and a protective film, which is a problem when a film made of a material containing polylactic acid is used as a protective film for a polarizing plate, to improve the adhesive force and to suppress the change in polarization degree with time. And a manufacturing method thereof. A polarizing plate in which a protective film made of a material containing polylactic acid is laminated on at least one surface of a polarizing film via an adhesive layer, and the adhesive layer is cured with a specific radiation curable composition. Shall. [Selection figure] None |
