Abstract: [Problem to be Solved] The present inventions provide a polarizing film and a polarizing sheet of which the resistance for the response in the vertical direction against the direction for the extension. [Means to Solve the Problem] In a multi-layered polarizing sheet comprising a laminated body in which a polarizing layer consisting of a polarizing film is held between two transparent plastic materials and is adhered to them, the polarizing layer is produced by dyeing a film made of poly(vinyl alcohol) and the like having a weight average molecular weight of 150,000-500,000 and by extending it. The non-glaring product and polarizing sheet for a liquid crystal display are produced by using the multi-layered polarizing sheet.

Abstract: The present invention provides a non-glaring material having an excellent property to cut ultraviolet rays, and having an excellent appearance and optical property as well as easy producibility and processibility, and a method for producing the non-glaring material. A non-glaring laminated body consisting of two transparent plastic material layers, a polarizing film layer which is held between the two transparent plastic material layers, and a synthetic adhesive layer which adheres the plastic material layer to the polarizing film layer, wherein at least one of the adhesive layers includes a fluorescent whitening agent and an ultraviolet ray absorber.
