Display panel and display device

A display panel, comprising:

• a substrate;
• a plurality of light emitting elements disposed on the substrate;
• each of the light emitting elements comprises a first electrode, a light emitting functional layer and a second electrode arranged along a direction perpendicular to the substrate and away from the substrate;
• and
• at least one transmissive-reflective module arranged on a side, close to the substrate, of the first electrode of at least one of the light emitting elements, and/or on a side, away from the substrate, of the second electrode of at least one of the light emitting elements;
• the transmissive-reflective module is configured to switch between a transmissive state and a reflective state,
• wherein the transmissive-reflective module comprises:
• a polarizer;
• a liquid crystal cell arranged on a side, away from the light emitting elements, of the polarizer, and configured to enable a polarization direction of polarized light passing through the liquid crystal cell to be unchanged or deflected by 90 degrees;
• a distributed Bragg reflective film layer arranged on a side, away from the light emitting elements, of the liquid crystal cell, and the distributed Bragg reflective film layer has a relatively high reflection characteristic on light with a polarization direction perpendicular to an absorption axis of the polarizer;
• the distributed Bragg reflective film layer has a relatively high transmission characteristic on light with a polarization direction parallel to the absorption axis of the polarizer.
