1. A display panel, comprising a display device and an anti-reflective layer disposed on the display device;
wherein the display device comprises a plurality of sub-pixel areas distributed in an array manner; and
the anti-reflective layer comprises a plurality of organic light-transmissive thin films corresponding to the sub-pixel areas, a plurality of inorganic nanoparticles are doped in the organic light-transmissive thin films, and the inorganic nanoparticles positioned at a side of the organic light-transmissive thin films away from the display device protrude from a surface of the organic light-transmissive thin films to form a plurality of nano moth-eye structures;
wherein the anti-reflective layer further comprises a plurality of light-shielding layers, a plurality of openings having a one-to-one correspondence relationship with the sub-pixel areas are formed on the light-shielding layers, and the organic light-transmissive thin films are disposed in the openings;
wherein the sub-pixel areas comprise a red sub-pixel area, a green sub-pixel area, and a blue sub-pixel area; and
the organic light-transmissive thin film corresponding to the red sub-pixel area is a red color resist, the organic light-transmissive thin film corresponding to the green sub-pixel area is a green color resist, and the organic light-transmissive thin film corresponding to the blue sub-pixel area is blue color resist.
