A novel polarizing element provided with a polarizing layer and a photo-alignment layer, a circular polarizer including the polarizing element, and a method for producing the same. A polarizer in which a photo-alignment layer and a polarizing layer are provided in this order on a transparent substrate, The photo-alignment layer is formed from a polymer having a photoreactive group, The polarizing layer is A polarizing element that is formed from a composition containing a polymerizable smectic liquid crystal compound and a dichroic dye, a circularly polarizing plate in which a retardation layer is further provided on the polarizing layer of the polarizing element, or the transparent of the polarizing element Providing a circularly polarizing plate in which the base material is replaced with a retardation film.
