Abstract:
A micro-louver (1) includes: a transparent substrate (2); a concavoconvex shape portion (5) formed on at least one surface of the transparent substrate (2) and in a prescribed pattern for diffracting incident light to form an image; and a light controlling layer (7) including at least one transparent layer (3) and at least light-absorption layer (4) arranged alternately on said at least one surface of the transparent substrate (2), each of said at least one transparent layer (3) and said at least one transparent layer (4) extending in a direction that intersects said at least one surface of the transparent substrate (2).
