ABSTRACT:
A scattering module and a backlight module comprising the scattering module are provided. The backlight module includes a plurality of light sources, while the scattering module includes a plurality of scattering elements. The scattering elements are disposed correspondingly to the light sources so that the scattering elements have different linearly arranged densities in different directions. Thereby, the light generated from the backlight module would be projected onto the display panel evenly with a uniform brightness.
