Abstract

A manufacturing method of a wire grid polarizer is provided, including: setting pattern data, where the pattern data correspond to a wire grid structure of the wire grid polarizer; preparing a metal ion solution; immersing at least one surface of a carrier substrate in the metal ion solution; and emitting, by an emitter device, an electron beam to the carrier substrate, and controlling a movement of the electron beam according to the pattern data to deposit a metal on the carrier substrate at a position where the electron beam passes, to form the wire grid structure.
