Claim:
1. A display panel, comprising: a reflector; a phase retarder arranged on the reflector and configured to change a polarization direction of a light beam passing through the phase retarder; a light-absorbing black matrix arranged on the phase retarder and configured to absorb the light beam; and a polarization scattering film arranged on the light-absorbing black matrix, wherein a polarized light beam emitted by a projector passes through the polarization scattering film and the phase retarder in sequence, and then reflected by the reflector and directed again to the polarization scattering film, so as to be scattered by the polarization scattering film, wherein the polarized light beam having passed through the polarization scattering film is transmitted along an original light path, and the polarization direction of the polarized light beam having passed through the phase retarder is changed by the phase retarder, and after passing through the polarization scattering film, a light beam with a polarization direction different from the polarization direction of the polarized light beam emitted by the projector is scattered by the polarization scattering film and then absorbed by the light-absorbing black matrix.
