The optical display device comprises a continuous web of polarizing film which is made of a polyvinyl alcohol type resin having a molecularly oriented dichroic material, and formed through stretching to have a thickness of 10 μm or less and satisfy conditions expressed by the following formulas: P>−(100.929T-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. The polarizing film may be prepared by subjecting a laminate comprising a non-crystallizable ester type thermoplastic resin substrate and a polyvinyl alcohol type resin layer formed on the substrate to by 2-stage stretching consisting of preliminary in-air stretching and in-boric-acid-solution stretching."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical display device having polarizing film","description":"Provided is an optical display device using a polarizing film which has a thickness of 10 μm or less and exhibits high optical characteristics.
