Abstract

A method of producing an absorbing polarizer which has a plurality of regions where directions of absorption axes are different from each other and has a curved surface portion. The method includes a step of forming a layer of a composition for forming a photo-alignment film that contains a photo-alignment agent on a surface of a resin base material, a step of forming the alignment film by irradiating the layer with ultraviolet rays of linearly polarized light via a lens, and aligning the photo-alignment agent, and a step of coating a surface of an alignment film with a composition containing a liquid crystal compound and a dichroic substance. The alignment film has a curved surface portion and a plurality of regions where directions of an alignment regulating force are different from each other.
