| 摘要 |
An object of the present invention is to improve uneven coloring by polarization color due to birefringence of a polarization optical article. Disclosed is a polarization optical article in which uneven coloring by polarization color has been improved, the polarization optical article being a multi-layered polarization optical article including at least a linear polarization functional portion, a retardation functional portion and a back-up resin portion, characterized in that the linear polarization functional portion, the retardation functional portion and the back-up resin portion are arranged in order from an objective side toward an ocular side. The linear polarization functional portion is, for example, a linear polarizer, the retardation functional portion is, for example, a retardation sheet, and the retardation functional portion has, for example, a retardation of 1,000 nm or more. The back-up resin is a polycarbonate resin, a polyamide resin or the like.
