Diffusers including of a plurality of protruded structures with each structure containing multiple rugged facets are disclosed. The diffuser may be fabricated by coating a mixture of materials on a carrier film, the mixture of materials including at least a first material that polymerizes upon irradiation and at least a second material that is incompatible with the first material in polymerized form, then selectively irradiating the mixture of materials to polymerize a portion of the mixture of materials to form polymerized structures, and finally removing that part of the mixture of materials not forming part of the structures. A transparent material may be coated over the structures. The overcoat material may further contain scattering elements such as glass beads or polymeric particles.
