Display panel, method for fabricating the same, and display device

A method for fabricating a display panel, comprising:

• forming sub-pixel units in at least two colors on a base substrate;
• and
• forming an anti-reflection layer on a side of the sub-pixel units away from the base substrate;
• wherein the anti-reflection layer comprises anti-reflection components arranged in an array, which correspond to the sub-pixel units in a one-to-one manner, and are configured to alleviate reflected light in same colors as the corresponding sub-pixel units, and sub-pixel units in different colors correspond to different anti-reflection components;
• wherein the forming the anti-reflection layer on the side of the sub-pixel units away from the base substrate comprises:
• coating a photoresist material on the side of the sub-pixel units away from the base substrate to form a photoresist material layer;
• and
• irradiating the photoresist material layer with exposure light rays using a preset mask to form the anti-reflection layer, wherein the exposure light rays comprise ultraviolet rays;
• wherein the preset mask comprises a plurality of zones arranged in an array;
• wherein the plurality of zones correspond to the sub-pixel units, and transmittivities for ultraviolet rays corresponding to respective zones are different, so that the photoresist material layer is irradiated with the exposure light rays in the respective zones to form anti-reflection components corresponding to the sub-pixel units.
