PATTERNED POLARIZING FILM AND ITS PRODUCTION PROCESS |
| 摘要 |
A patterned polarizing film is provided for obtaining a thin patterned circular polarizing plate having a superior anti-reflection property. The film includes a substrate and a patterned liquid crystal cured layer laminated thereon. The layer contains a polymer of a polymerizable liquid crystal compound(s) and a dichroic dye. The patterned polarizing film includes a region (A) having a degree of polarization of 10% or lower and a single transmittance of 80% or higher, and a region (B) having a degree of polarization of 90% or higher and a single transmittance of 40% or higher. |

1. A patterned polarizing film comprising a laminate of a substrate and a patterned liquid crystal cured layer comprising a dichroic dye and a polymer of a polymerizable liquid crystal compound(s), the patterned polarizing film has one or more regions (A) and one or more regions (B),
wherein the patterned polarizing film has a region (A) having a degree of polarization of 10% or lower and a single transmittance of 80% or higher, and a region (B) having a degree of polarization of 90% or higher and a single transmittance of 40% or higher. |
