ABSTRACT:
A polarizing plate which has a polarizing layer having a thickness of about 20 nm to about 1500 nm formed by rubbing at least one surface of a substrate, coating the rubbed surface of the substrate with an aqueous solution containing a dye having a tabular molecular shape, and drying the solution. This polarizing plate is a thinner polarizing plate with a high degree of polarization and suitably applicable to portable electronic equipment such as cellular phones, portable information terminals, smart cards and IC cards.
