The present invention relates to a kind of polarizers and the method for preparing the polarizer, have the preparation method of the polarizer in the region that depolarizes more particularly, to a kind of part, the described method comprises the following steps：Offer iodine and/or the polaroid based on polyvinyl alcohol of dichroic dyestuff dyeing；Protective film and release film are equipped on a surface of the polaroid；And make another surface of polaroid described in de-inking solution localized contact; it depolarizes region to form one or more; wherein; the release film is provided on the surface opposite with the surface towards the polaroid of the protective film; the region that depolarizes has 80% or more monomer transmissivity and 10% degree of polarization below at the wavelength band of 400nm to 800nm, and the maximum cup depth in the region that depolarizes is 10 μm or less. |
