摘要： 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.

摘要翻译： 提供了包括光入射面和光射出面的光扩散装置。 光出射表面具有至少一种光散射图案。 光散射图案的轨迹是连续曲线。 缠绕连续曲线以在光出射表面上依次形成多个封闭图案，并且两个相邻的封闭图案至少部分重叠。
