Abstract:
The present invention addresses the problem of providing a thin polarizing plate having a favorable degree of polarization, a method for manufacturing the same, and an image display device that uses the polarizing plate. This polarizing plate is a polarizing plate in which a hard-coat layer is directly laminated on a polarizer, wherein the polarizing plate is characterized in that thickness of the polarizer is 0.5 μm to 10 μm, and the pencil hardness of the hard-coat layer ranges from B to H.
