1. A display panel, comprising:
a substrate,
a plurality of sub-pixels on a side of the substrate;
an encapsulation layer on a side of the plurality of sub-pixels away from the substrate, wherein the encapsulation layer covers the plurality of sub-pixels;
a light shielding layer on a side of the encapsulation layer away from the substrate, wherein the light shielding layer is provided with a plurality of openings corresponding to the plurality of sub-pixels respectively;
a first color film layer comprising a plurality of basic units covering the plurality of openings in the light shielding layer respectively; and
a second color film layer on a side of the first color film layer away from the substrate, wherein the second color film layer comprises a plurality of overlay units covering an edge of at least one basic unit of the plurality of basic units respectively, wherein a color of the basic unit is different form a color of the overlay unit covering the basic unit;
wherein the plurality of basic units comprises at least one red basic unit, at least one green basic unit and at least one blue basic unit, and the plurality of overlay units comprises at least one first blue overlay unit corresponding to the at least one red basic unit respectively and at least one second blue overlay unit corresponding to the at least one green basic unit respectively;
wherein at least a part of an edge of the red basic unit is covered by the first blue overlay unit corresponding to the red basic unit; and
wherein at least a part of an edge of the green basic unit is covered by the second blue overlay unit corresponding to the green basic unit.
