Abstract: 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 film on one side comprises a lactone ring structure-containing (meth)acrylic resin and has an in-plane retardation of less than 40 nm and a thickness direction retardation of less than 80 nm, and the transparent protective film on the other side is a retardation plate that comprises a cellulose ester and satisfies the relation: nx>ny>nz, wherein nx is a refractive index in an X-axis direction where the in-plane refractive index is maximum, ny is a refractive index in a Y-axis direction perpendicular to the X-axis, and nz is a refractive index in a Z-axis direction corresponding to the thickness direction. The polarizing plate can satisfy durability and display uniformity (unevenness).

Abstract: A polarizer of the invention comprises a polyvinyl alcohol-based film which is at least dyed with at least iodine and uniaxially stretched, having a single transmittance of 43% or more, a polarizing efficiency of 99.9% or more, and a dichroic ratio of 30 or more, wherein the dichroic ratio is calculated from a parallel transmittance (Tp) and a crossed transmittance (Tc) at a wavelength of 440 nm, and have good hue.
