Claim 7:
8. The display panel according to claim 1, wherein on a direction perpendicular to the display panel, the first display region comprises: a substrate, a drive structure layer disposed on the substrate, a light-emitting structure layer disposed on a side of the drive structure layer away from the substrate, a thin film encapsulation layer disposed on a side of the light-emitting structure layer away from the substrate, a light extraction structure layer disposed on a side of the thin film encapsulation layer away from the substrate, a low-refractive-index reflecting layer covering the light extraction structure layer, and a color filter layer disposed on a side of the low-refractive-index reflecting layer away from the substrate,
wherein the light-emitting structure layer comprises a plurality of first light-emitting elements, wherein the first light-emitting elements respectively emit light along the first light-emergence direction, the second light-emergence direction and the third light-emergence direction;
the light extraction structure layer comprises a plurality of first collimating light extraction elements and a plurality of second collimating light extraction elements, wherein each first collimating light extraction element is located in the second light-emergence direction of the first light-emitting element corresponding to the first collimating light extraction element; each second collimating light extraction element is located in the third light-emergence direction of the first light-emitting element corresponding to the second collimating light extraction element; and
the color filter layer comprises a plurality of first filter units, a plurality of second filter units and a plurality of third filter units, wherein each first filter unit is located in the first light-emergence direction of the first light-emitting element corresponding to the first filter unit; each second filter unit is located in the light-emergence direction of the first collimating light extraction element corresponding to the second filter unit; and each third filter unit is located in the light-emergence direction of the second collimating light extraction element corresponding to the third filter unit.
