POLARIZING PLATE |
| 摘要 |
A polarizing plate according to an embodiment of the present invention includes a laminate produced by laminating a resin substrate having a percentage of water absorption of 0.2% or more and 3.0% or less and a glass transition temperature of 60° C. or more on one side of a polyvinyl alcohol-based film having a thickness of 30 μm or less, the laminate being subjected to dyeing treatment and stretching treatment including at least in-boric-acid-solution stretching. The polyvinyl alcohol-based film serves as a polarizing film and the resin substrate serves as a protective film for the polarizing film. |
