Polarizer, method of manufacturing polarizer and liquid crystal projector

Abstract

A polarizer capable of being manufactured in simple steps, and a method of manufacturing the polarizer, as well as a liquid crystal projector are provided. The polarizer includes a substrate having light permeability, and a plurality of linear projections being arranged on the substrate and extending along one direction within a plane thereof. Each of the linear projections having a base layer and a plating layer in the named order from the substrate, the base layer containing a catalyst material for electroless plating process, and the plating layer being deposited by using the base layer as a catalyst.

         4 . A method of manufacturing a polarizer having the step of forming a plurality of linear projections on a light permeable substrate so as to extend in one direction within the plane thereof, the method comprising the steps of:
 pattern forming a base layer containing a catalyst material for electroless plating process in a region for forming a plurality of linear projections on the substrate; and   forming the plurality of linear projections by forming a plating layer on the base layer by performing electroless plating process using the base layer as a catalyst, to the substrate provided with the base layer.   
     
     
         5 . The method of manufacturing a polarizer according to  claim 4 , wherein
 the step of pattern forming the base layer includes the steps of:   fabricating a plate by using a mold, the plate having on a surface thereof a concave-convex pattern corresponding to the region for forming a plurality of linear projections;   forming a catalyst layer containing the catalyst material, on a surface of the plate; and   transferring the catalyst layer onto the region for forming a plurality of linear projections on the substrate by pressure-bonding a convex surface of the concave-convex pattern of the plate provided with the catalyst layer, against the substrate.   
     
     
         6 . The method of manufacturing a polarizer according to  claim 4 , wherein
 the step of pattern forming the base layer includes the steps of:   forming a catalyst layer containing the catalyst material, on a surface of a flat plate;   allowing a second catalyst layer corresponding to the region for forming the plurality of liner projections to remain on the flat plate by pressure-bonding a convex surface of a plate having a concave-convex pattern against the flat plate provided with the catalyst layer, and transferring a first catalyst layer onto the convex surface; and   transferring the second catalyst layer onto the substrate by pressure-bonding the flat plate with the second catalyst layer remaining thereon, against the substrate.
