1. A display panel, wherein the display panel comprises:
a driving backplane;
a light-emitting-device layer, wherein the light-emitting-device layer is provided on the driving backplane; and
a packaging layer, a color-film layer and a light absorbing layer, wherein the packaging layer, the color-film layer and the light absorbing layer are provided on one side of the light-emitting-device layer that is further away from the driving backplane;
wherein the light absorbing layer is configured for absorbing light rays of a specific wavelength in external-environment light and in light rays emitted by the light-emitting-device layer; and
the specific wavelength includes at least one of a wavelength between a red-light wave band and a green-light wave band, a wavelength between a green-light wave band and a blue-light wave band, a wavelength shorter than a blue-light wave band and a wavelength longer than a red-light wave band;
wherein the light-emitting-device layer comprises an anode layer provided on the driving backplane and a pixel defining layer provided on the anode layer, the pixel defining layer has a plurality of opening regions, and a material of the pixel defining layer is a black light shielding material;
the light-emitting-device layer further comprises an organic functional layer provided within the opening regions, and a cathode layer covering the pixel defining layer and the organic functional layer; and
the light-emitting-device layer further comprises a light shielding layer provided between the pixel defining layer and the cathode layer, and the light shielding layer is located on a surface of one side of the pixel defining layer that is further away from the driving backplane; and
a material of the light shielding layer is a black light shielding material.
