Patent ID: 7248331

Claim:
A polarizer comprising a film having a structure having a minute domain dispersed in a matrix formed of a translucent thermoplastic resin including an absorption dichroic dye, wherein a transmittance to a linearly polarized light in a transmission direction is 80% or more, a haze value is 10% or less, a haze value to a linearly polarized light in an absorption direction is 50% or more, the translucent thermoplastic resin is a polyvinyl alcohol, and the minute domain is formed of an oriented birefringent material that shows liquid crystalline at least in orientation processing step, wherein the birefringent material forming the minute domain is a liquid crystalline thermoplastic resin showing up a state of a nematic phase or a smectic phase in a temperature region lower than a glass transition temperature of the translucent thermoplastic resin.
