摘要：There is provided a polarizer constituted by: a polarizing element; and at leastone transparent protective film constituted by two layers of retardation films with an in-plane retardation in a range of from 190 to 320 nm with respect to light having awavelength of 550 nm, the transparent protective film being bonded onto one ofopposite surfaces of the polarizing element so that a slow axis of each of the retardationfilms is parallel with an absorption axis of the polarizing element, the two layers ofretardation films being constituted by a combination of a retardation film with Nz of from0.65 to 0.85 and a retardation film with Nz of from 0.15 to 0.35 on the condition of nx>nyand Nz=(nx−nz)/(nx−ny) in which nx and ny are in-plane refractive indices of each of theretardation films respectively, and nz is a refractive index in a direction of thickness ofeach of the retardation films.
