Abstract
A method for manufacturing a metal wire grid polarizer includes providing a template having grooves; forming a metal layer in the grooves, which comprises coating a metal thin film on a surface of the template on which the grooves are provided, and impressing the metal thin film so that the metal thin film is filled in the grooves to form a metal wire grid structure, the metal wire grid structure comprising the metal layer formed in the grooves and a cladding layer integrated with the metal layer and covering the surface of the template; and moving the metal layer to a substrate to manufacture the metal wire grid polarizer.
