As the particle size of the scattering particles becomes larger, the incident light gradually undergoes the conversion from rayleigh scattering to mie scattering. Therefore, by using this theory, the light path and scattering of the blue light are increased by providing the scattering film 1031 in which scattering particles with different particle sizes are continuously layered, so as to achieve the purpose of improving the viewing angle of the blue light.
