Abstract

A polarizing element or polarizing plate comprising a layer having photoactive molecules and a layer containing dichroic molecules formed in contact with said layer, which can easily be produced without a stretching procedure so as to have a complicated pattern, a curved surface or a large area; and a process for producing said polarizing element or polarizing plate which is characterized by irradiating a layer having photoactive molecules on a substrate with linear polarized light, and then forming a dichroic molecular layer on the irradiated layer.
