Abstract
A composite film module, a method for manufacturing the same, a light collecting device and a display device are provided. Each composite layers includes first and second refractive index layers, and a refractive index of the first refractive index layer is greater than that of the second refractive index layer. One first refractive index layer is provided between every two adjacent second refractive index layers. Along a thickness direction of a composite film module, first and second composite layers are adjacent to each other, a refractive index of the first refractive index layer in the first composite layer is greater than that of the first refractive index layer in the second composite layer, and the refractive index of the second refractive index layer in the first composite layer is greater than that of the second refractive index layer in the second composite layer.
