Summary: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.
