Abstract

A method for manufacturing a polarizer is disclosed. The method comprises: providing a liquid crystalline mixture comprising reactive molecules, non-reactive molecules, dichroic dye molecules, and a polymerization initiator; providing a uniaxially oriented film of said mixture; polymerizing said film; and removing at least part of said non-reactive molecules. Also disclosed are polarizers manufactured by such a method, as well as optical devices comprising such polarizers.
