PROBLEM TO BE SOLVED: To obtain an optical member which is able to form a liquid crystal display device for mobile use with excellent reliability by obtaining a polarizing plate which maintains durability being a match for, and enables to be thinner and lighter in weight, than the conventional one, and which attains improved durability without deteriorating cutting workability or the like. SOLUTION: The method for manufacturing a polarizing plate comprises coating one or both surfaces of a polarizing film 2 composed of a hydrophilic polymer with a resin solution whose solvent does not dissolve the film and drying it so as to provide transparent thin film layers 1, 3, and the polarizing plate comprises the polarizing film having transparent thin film layers composed of the resin coated film on its one or both surfaces and having protection layers composed of a transparent film thereon. The optical member comprises the polarizing plate formed by this method or a laminated body composed of the polarizing plate and an optical layer exhibiting other optical functions and the liquid crystal display device comprises a liquid crystal cell having the optical members arranged on its one or both sides. Thereby thin films are easily formed by the coating film method and the protection layers, tightly adhered to the polarizing film and excellent in being thin and light in weight, are formed without interposing any adhesive layer. |
