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 original plate allowing easy and mass production of an alignment layer with which a high-quality pattern retardation film for a three-dimensional display device can be formed.

SOLUTION: The method includes: a first layer formation step of forming a first layer made of metal; a first concavo-convex structure formation step of forming a minute linear concavo-convex structure approximately in a given direction on the surface of the first layer; a resist formation step of forming a resist in parallel strips on the surface of the first layer; a second layer formation step of forming a second layer comprising an inorganic material by subjecting the surface of the resist and of the exposed first layer to dry plating; a peeling step of peeling the resist; a protective layer formation step of forming a protective layer by subjecting the exposed first layer to wet plating; a second concavo-convex structure formation step of forming a minute linear concavo-convex structure approximately in a given direction on the surface of the second layer, the given direction different from the direction in the first concave-convex structure formation step; and a peeling step of peeling the protective layer.
