Abstract
A composite optical film is provided. The composite optical film sequentially includes a substrate, a light diffusion layer, and a light-gathering layer. The light diffusion layer includes a binder and plural micro beads dispersed therein. The thickness of the light diffusion layer is 2-6 times of the average diameter of the micro beads, and the distance between adjacent micro beads is smaller than the average diameter of the micro beads. The light-gathering layer has plural light-gathering micro structures.
