摘要： Curable compositions include at least one fluoropolymer, at least one monofunctional (meth)acrylate, at least one difunctional (meth)acrylate, and at least one initiator. The curable composition, when cured, forms an optically-scattering layer including a matrix and phase separated microdomains. The matrix and the phase separated microdomains have different refractive indices, and the microdomains are on the order of or larger than the wavelengths of visible light.
