WIRE-GRID POLARIZER, METHOD FOR PRODUCING THE WIRE-GRID POLARIZER, RETARDATION FILM AND LIQUID CRYSTAL DISPLAY DEVICE USING THE RETARDATION FILM

摘要

A method for producing a wire-grid polarizer includes the steps of preparing a resin film including a concave part formed thereon, the concave part having a submicron-sized grating pattern, the resin film having a visible light transmittance of 80% or more; filling the concave part with an electroconductive nano-material having an average diameter equal to or smaller than one-half of an average line width of the concave part; and removing the electroconductive non-material which has not been filled into the concave part.
