    Abstract: A display substrate, a manufacture method thereof and a transparent display device are provided. The display substrate includes a substrate (1); a plurality of pixel regions, each including a plurality of sub-pixel regions; and a first metallic layer (3), a passivation layer (5) and a second metallic layer (4) that are formed on the substrate in sequence and are located at the sub-pixel regions. The first metallic layer (3) and the second metallic layer (4) both are transflective metallic layer, and different parts of the passivation layer located at the plurality of sub-pixel regions of a same pixel region have different thicknesses. The first metallic layer (3), the passivation layer (5) and the second metallic layer (4) constitute a Fabry-Perot cavity which allows light having different wavelengths to transmit there-through depending on different thicknesses of different parts of the passivation layer.

    Abstract: The present disclosure provides a display panel, including: a reflector; a phase retarder configured to change a polarization direction of a light beam passing through the phase retarder; a light-absorbing black matrix configured to absorb the light beam; and a polarization scattering film. After passing through the polarization scattering film, a polarized light beam from a projector is transmitted along an original light path, then the polarized light beam is transmitted through the phase retarder, reflected by the reflector and directed again to the polarization scattering film so as to be scattered. After passing through the polarization scattering film, a light beam with a polarization direction different from the polarized light beam from the projector is scattered by the polarization scattering film and then absorbed by the light-absorbing black matrix.
