    摘要： A polarizer that can be used for forming a liquid crystal display or an electroluminescent display with less display irregularities and excellent display characteristics is provided. The polarizer contains a dichroic material in a matrix, and its in-plane retardation at a measurement wavelength providing no absorption is in a range of 950 to 1350 nm. The measurement wavelength is preferably a wavelength that the dichroic material provides no absorption, and it is 1000 nm, for example.

    摘要： A method of producing a polarizing plate of the present invention comprises the steps of: bonding a protective film to at least one side of a polarizing film that is produced through at least uniaxial stretching and has an absorption axis in the uniaxial stretching direction, and removing by cutting at least one of the edges of the polarizing film that are substantially parallel to the direction of the absorption axis before the bonding the protective film. The method widen the effective width of the polarizing plate, and a large size polarizing plate was obtained.

    摘要： The present invention provides a method for manufacturing a polarizing film, by which, even when a wide raw film is used, it is possible to obtain a polarizing film that achieves excellent optical characteristics as well as uniformity in in-plane optical characteristics. The method includes the steps of dyeing a polymer film; stretching the dyed film; and drying the film that has undergone the dyeing and stretching steps while conveying the film with rolls. In the drying step, at least two rolls are used as the rolls and the film is dried under a condition that a ratio (R/W) of a distance (R) between the adjacent rolls to an initial width (W) of the polymer film is not less than 0.5 and not more than 4.0.
