Claim 14:
15. 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; and
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, wherein the liquid crystal cell further includes:
a first alignment layer disposed on the first substrate and on a side of the first substrate proximate to the liquid crystal layer, the first alignment layer having a first alignment direction; and
a second alignment layer disposed on the second substrate and on a side of the second substrate proximate to the liquid crystal layer, the second alignment layer having a second alignment direction,
wherein the first alignment direction is parallel to the second alignment direction, and the second alignment direction is perpendicular to the transmission axis of the second polarization structure.
