Patent ID: 8520171

Claim:
An optical display device comprising: a first polarizing film made of comprising a layer of a polyvinyl alcohol type resin, said layer of polyvinyl alcohol type resin including dichroic material impregnated therein in a molecularly oriented dichroic material therein state, said first polarizing film having a thickness of 10 μm or less with oriented molecules of the polyvinyl alcohol type resin layer, the dichroic material impregnated in the polyvinyl alcohol type resin layer being iodine present in the form of poly-iodine ion complex oriented in the polyvinyl alcohol type resin layer substantially in one direction, the first polarizing film having optical properties and satisfying conditions expressed by the following formulas: P >−(10 0.929T-42.4 −1)×100 (where T <42.3); and P ≧99.9 (where T≧42.3), wherein T is a single layer transmittance, and P is a polarization rate; a display panel having a first surface and a second surface opposite the first surface; an optically transparent adhesive layer configured to join a first surface of the first polarizing film the first surface display panel; and a protective layer, the first polarizing film having a second surface, opposite the first surface, joined to the protective layer.
