    Abstract: A method for patterning film layer, a metal wire grid polarizer and a manufacturing method thereof are provided. The method includes: forming an imprint adhesive layer on a metal layer; imprinting the imprint adhesive layer to form a groove so that part of the metal layer is exposed from the bottom of the groove; performing a surface treatment on the exposed metal layer to form an etching-resist layer on the surface of the exposed metal layer, the etching-resist layer containing an element contained in the metal layer; and etching the imprint adhesive layer and the surface-treated metal layer to remove the imprint adhesive layer and the metal layer whose surface is not formed with the etching-resist layer, to obtain a patterned metal layer, thereby reducing cost and time of the metal layer patterning and improving the patterning accuracy.

    Abstract: A sealant composition includes: a main component; and a high strength fiber with a specific surface area of about 2000 m2/g to about 30000 m2/g, wherein the amount of the high strength fiber is about 0.5% to about 3% based on the weight of the main component. The high strength fiber has a high specific surface area and has active groups such as a hydroxyl group and a carboxyl group on its surface, and allows the fiber resin matrix to form a chemical bond at the interface, thereby improving the reaction ability and bonding strength of the fiber resin matrix, and enhancing the overall strength of the uncured sealant, and mitigating the phenomenon of liquid crystal puncturing.
