摘要：
Light redirecting film including a thin optically transparent substrate having a pattern of individual optical elements of well-defined shape on at least one surface that are quite small relative to the length and width of the surface. At least some of the optical elements have at least one flat surface and at least one curved surface, and intersecting each other over an intersection volume of the intersecting optical elements.
