Abstract

The present disclosure provides a display device, including: a driving backplane; a light emitting layer, disposed on a side of the driving backplane, and including a plurality of light emitting devices that include a first light emitting device emitting light of a first color; a chiral liquid crystal layer, disposed on a side of the light emitting layer away from the driving backplane, and configured to transmit circularly polarized light of the first color in a first handedness and reflect circularly polarized light of the first color in a second handedness; and a circularly polarization layer, disposed on a side of the chiral liquid crystal layer away from the driving backplane, and configured to convert light incident from a side of the circularly polarization layer away from the driving backplane into the circularly polarized light in the first handedness.
