Abstract
An enhanced light diffusion film structure includes a first substrate, a second substrate, a first light guide diffusion layer and a second light guide diffusion layer. The first light guide diffusion layer includes a first light guide diffusion material having a first degree of light guide diffusion to guide and diffuse incident light exited by the first substrate to form first-stage guided and diffused light. The second light guide diffusion layer includes a second light guide diffusion material having a second degree of light guide diffusion to further guide and diffuse the first-stage guided and diffused light exited by the first light guide diffusion layer to form second-stage guided and diffused light. The first degree of light guide diffusion of the first light guide diffusion material is relatively higher or lower than the second degree of light guide diffusion of the second light guide diffusion material.
