摘要: A polarizer of the present invention comprises stretched film that is obtained from a by subjecting to at least dyeing treatment with dichroic material and stretching treatment, wherein made mixture containing polyvinyl alcohol-based resin polycarboxylic acid compound having two or more carboxyl groups and/or one anhydride molecular weight 1,000 less. The can suppress degradation in optical properties minimum even high temperature.
