Abstract:
An optical sheet having a structured surface and a composition for forming optical three-dimensional patterns able to form the structured surface, which is not easily damaged by external force or a rough surface and thus facilitates the handling thereof, reduces defective rates to thus decrease the production cost and increase the production efficiency, and prevents a decrease in luminance attributable to damage.
