ABSTRACT:
A light diffusion device including a light incident surface and a light exit surface is provided. The light exit surface has at least one light scattering pattern. A trajectory of the light scattering pattern is a continuous curve. The continuous curve is winded to form a plurality of closed patterns in sequence on the light exit surface, and two adjacent closed patterns at least overlap partly.
