    摘要: A polarizer that can be used for forming a liquid crystal display or an electroluminescent display with less display irregularities and excellent display characteristics is provided. The polarizer contains a dichroic material in a matrix, and its in-plane retardation at a measurement wavelength providing no absorption is in a range of 950 to 1350 nm. The measurement wavelength is preferably a wavelength that the dichroic material provides no absorption, and it is 1000 nm, for example.

    摘要: A polarizing plate of the present invention includes a polyvinyl alcohol-based polarizer and transparent protective films provided on both sides of the polarizer with an adhesive layer interposed between the polarizer and each transparent protective film, wherein the transparent protective films each comprise a lactone ring structure-containing (meth)acrylic resin, each one of the transparent protective films has a thickness T1 (μm) of 10 to 35 μm, and the polarizer has a thickness T2 (μm) which satisfies that the ratio (T2/T1) of T2 to the thickness T1 of each one of the transparent protective films falls within the range of 0.8 to 1.8. The polarizing plate is designed to be thin and can satisfy durability.
