Abstract
A method for producing a mold for a patterned alignment film for three-dimensional display includes: forming a first layer composed of a metal material or an inorganic material; forming a fine linear three-dimensional structure in a surface of the first layer in an approximately constant direction;F forming a second layer, composed of a metal material or an inorganic material, on the surface of the first layer after the first three-dimensional structure forming step; a second three-dimensional structure forming step of forming a fine linear three-dimensional structure in a surface of the second layer in an approximately constant direction which differs by 90° from that in the first three-dimensional structure forming step; a resist forming step of forming a resist in a parallel stripe pattern on the surface of the second layer after the second three-dimensional structure forming step.
