摘要：
A polarizing film includes a polyvinyl alcohol (PVA) type resin having a dichroic material impregnated therein. The polarizing film is formed by stretching the PVA type resin, such that the thickness of the polarizing film is decreased to 10 μm or less, and. The polarizing film has optical properties which satisfy conditions represented by formulae: P>−(100.929T-42.4−1)×100 (where T
