WIRE GRID POLARIZER, METHOD FOR MANUFACTURING WIRE GRID POLARIZER, PROJECTION DISPLAY DEVICE, VEHICLE, AND PHOTO-CURABLE ACRYLIC RESIN FOR IMPRINTING

WIPO Patent Application WO/2023/120735

A1

[Problem] To provide a wire grid polarizer having an excellent heat dissipation characteristic as well as excellent transmission and polarization splitting characteristics with respect to obliquely incident light over a wide range of incidence angles. [Solution] A wire grid polarizer 1 comprises: a substrate 10 made of an inorganic material; a grid structure 20 which is made of an organic material, and in which a base part 21 and a plurality of ridges 22 provided on the substrate 10 are integrally formed; and a functional film 30 which is made of a metal material, and partially covers the ridges 22. Each of the ridges 22 has a tapered shape with a width gradually decreasing as the distance from the base part 21 increases. The functional film 30 wraps a top of each ridge 22, and does not cover a bottom side of the ridge 22 and the base part 21. The coverage ratio (Rc) of a side surface of the ridge 22 by the functional film 30 is not less than 30% and not more than 70%. The organic material is a cured product of a photo-curable acrylic resin for imprinting, containing a photopolymerizable component.
