Method for manufacturing metal wire grid polarizer and display panel

A display panel comprising a metal wire grid polarizer manufactured using a method for manufacturing the metal wire grid polarizer, the method comprising:

• providing a template having grooves;
• forming a metal layer in the grooves by 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;
• wherein moving the metal layer to the substrate comprises:
• providing the substrate on the cladding layer and bonding the metal wire grid structure to the substrate;
• separating the metal wire grid structure bonded to the substrate from the template;
• and
• etching the metal wire grid structure to etch away the cladding layer between the adjacent metal layers and expose a surface of the substrate, to obtain the metal wire grid polarizer.

• coating an impact-resistance layer on a surface of the metal thin film;
• and
• impressing the impact-resistance layer and the metal thin film by using an impressing device so that the metal thin film is filled in the grooves and is formed into the metal wire grid structure;
• and
• moving the metal layer to a substrate to manufacture the metal wire grid polarizer, wherein the impressing device is a laser.
