Estimating the term…
An anti-reflective film has an anti-reflective structure having many micro holes extending from a reference surface (first surface) in the thickness direction of the film. Each of the holes has an opening exposed at the reference surface, and a bottom facing the second surface on the attachment side. Light incident on the anti-reflective film is mostly introduced into the holes through the openings and diffused by the bottoms, thereby avoiding reflection at a predetermined angle. The ratio of a connecting surface which reflects light is suppressed to increase the ratio of the openings, thereby maximizing the anti-reflective ability of the anti-reflective structure.
An anti-reflective structure comprising many micro holes each having an opening at a first surface and a bottom facing a second surface opposite to the first surface, each hole extending from the opening to the bottom.
A light guide comprising:
A mold for forming an anti-reflective film comprising an anti-reflective structure having many micro holes each having an opening at a first surface and a bottom facing a second surface opposite to the first surface, each hole extending from the opening to the bottom, the mold comprising a first inner surface for forming the first surface, a second inner surface for forming the second surface, and many micro protrusions protruding from the first inner surface to the second inner surface for patterning the outlines of the holes.
