PRODUCTION METHOD OF ORIGINAL PLATE FOR PATTERN ALIGNMENT LAYER FOR THREE-DIMENSIONAL DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide a production method of an original plate for a pattern alignment layer for three-dimensional display, the method aiming at easy and mass production of a pattern alignment layer with which a high-quality pattern retardation film for three-dimensional display can be formed.

SOLUTION: The production method of an original plate for a pattern alignment layer for three-dimensional display includes steps of: preparing a base layer 1 made of a metal material; forming a resist 2 in parallel strips on the surface of the base layer; forming a first layer 3 having a patter of parallel strips by subjecting the base layer and the resist to dry plating to form an inorganic material layer 3' having insulating property and then peeling a laminate of the resist and the inorganic material layer; forming a first concavo-convex structure 31 by forming a minute linear concavo-convex structure in approximately a given direction on the surface of the first layer; forming a second layer 4 comprising a metal material having a thickness equal to or larger than the thickness of the first layer by subjecting the exposed base layer to wet plating; and forming a second concavo-convex structure 41 having a minute linear concave-convex structure on the surface of the second layer in a formation direction different from the formation direction of the first concavo-convex structure.
