Polarized light source assembly

The invention discloses a polarized light source assembly which is provided with a central region and a peripheral region located on at least one side of the central region. The polarized light source assembly comprises a lamp casing, at least one light source, a polarization sheet and a fine structure layer. The light source is arranged at the peripheral region, the polarization sheet is arranged in the periphery region and used for polarizing a light emitted by the light source, and the fine structure layer is arranged at the central region and used for enabling the light polarized by the polarization sheet to be reflected to the direction away from the lamp casing.
