SELF-SUPPORTING FILM, SELF-SUPPORTING STRUCTURE, METHOD FOR MANUFACTURING SELF-SUPPORTING FILM, AND PELLICLE

摘要

Provided is a self-supporting film having excellent optical characteristics as a result of being independently provided with an anti-reflection function. The self-supporting film comprises a concave-convex structure layer in which concave and convex shapes are periodically formed in the surface thereof, wherein the concave and convex shapes are periodically formed on at least one side of the concave-convex structure layer, the self-supporting film has an average thickness in the range of 0.2 µm to 20.0 µm, and the concave-convex structure layer has a yield strain of 1% or higher and a tensile elongation of 10% or higher.
