Abstract
The invention provides a method for manufacturing a metal wire grating polaroid, and the method comprises the steps: providing a substrate and an imprinting template, wherein the imprinting template comprises a plurality of parallel and separated pattern columns, a pattern trench is formed between each two adjacent pattern columns, and the substrate comprises a base plate and a volatilization liquid layer disposed on the base plate in a coating manner; placing nanoparticle mixed liquid in the pattern trenches, wherein the nanoparticle mixed liquid comprises a dispersing agent and nanoparticlesscattered in the dispersing agent; heating the nanoparticle mixed liquid so as to enable the nanoparticles in the nanoparticle mixed liquid to be stacked in the pattern trenches to form a plurality of nanoparticle columns; placing the imprinting template where the plurality of nanoparticle columns are staked on the substrate, wherein the plurality of nanoparticle columns make contact with the substrate; enabling the volatilization liquid layer to volatilize so as to enable the plurality of nanoparticle columns to be solidified on the substrate; and removing the imprinting template. The methodsolves the technical problems that a conventional manufacturing method for the metal wire grating polaroid is complex, is long in manufacturing time, and wastes time.
Description
technical field [0001] The invention relates to the technical field of polarizers, in particular to a method for manufacturing a metal wire grid polarizer and the metal wire grid polarizer. Background technique [0002] In the field of display technology manufacturing, the current method of preparing a metal wire grid polarizer mainly includes the following main steps: depositing a metal film on a substrate, depositing a photoresist layer on the metal film, embossing the photoresist layer, and curing the photoresist layer removing the remaining photoresist layer and dry-etching the metal thin film with the photoresist layer as a mask to obtain metal lines, and the metal lines and the substrate form a metal wire grid polarizer. However, this method has a complicated process and a long process time, which is a waste of time. Contents of the invention [0003] The object of the present invention is to provide a method for manufacturing a metal wire grid polarizer and a metal...
