Claim 0:
1. A display panel, comprising:
a liquid crystal cell including a first substrate, a second substrate and a liquid crystal layer, wherein the first substrate and the second substrate are disposed opposite to each other, and the liquid crystal layer is sandwiched between the first substrate and the second substrate;
an optical layer disposed on a side of the first substrate of the liquid crystal cell away from the second substrate, wherein the optical layer is configured to transmit part of light incident onto the optical layer whose polarization direction is parallel to a transmission axis of the optical layer, and reflect a remaining part of the light incident onto the optical layer;
a first polarization structure disposed on a side of the optical layer away from the liquid crystal cell, wherein the first polarization structure is configured to transmit part of light incident onto the first polarization structure whose polarization direction is parallel to a transmission axis of the first polarization structure, and absorb a remaining part of the light incident onto the first polarization structure;
a second polarization structure disposed on a side of the liquid crystal cell away from the optical layer, wherein the second polarization structure is configured to transmit part of light incident onto the second polarization structure whose polarization direction is parallel to a transmission axis of the second polarization structure, and absorb a remaining part of the light incident onto the second polarization structure; and the transmission axis of the first polarization structure is perpendicular to the transmission axis of the optical layer, and the transmission axis of the second polarization structure is perpendicular to or parallel to the transmission axis of the optical layer; and
a scattering film disposed on a side of the liquid crystal cell proximate to the optical layer and between the liquid crystal cell and the optical layer,, wherein the optical layer includes:

a plurality of first optical films, the plurality of first optical films being birefringent; and
a plurality of second optical films, the plurality of second optical films being single-refractive, wherein in a direction perpendicular to a plane where the display panel is located, the plurality of first optical films and the plurality of second optical films are alternately stacked,

wherein one of a first optical film in the plurality of first optical films and a second optical film in the plurality of second optical films is directly bonded to the scattering film.
