Abstract
A polarizer used for an image display such as a liquid crystal display, a plasma display, and an electroluminescence display, and the polarizer suppresses coloring of transmitted light. The polarizer includes a polymer film having a difference of 10% or less between the maximum and the minimum of a first transmittance in a wavelength ranging from 400 nm to 700 nm.
