1. A method for manufacturing a display panel, comprising:
sequentially preparing an anode layer and a first pixel define layer on a surface of a substrate layer;
coating an organic light-induced material on a surface, distal from the anode layer, of the first pixel define layer, and forming a polymer film layer by reacting the first pixel define layer with the organic light-induced material under a predetermined condition, wherein the organic light-induced material at least comprises a hydroxyl group and an unsaturated carbon-carbon double bond; and
preparing an organic functional layer and a cathode layer, wherein both the organic functional layer and the cathode layer are disposed on a surface, distal from the first pixel define layer, of the organic light-induced material;
wherein the predetermined condition at least comprises ultraviolet light irradiation;
wherein forming the polymer film layer by reacting the first pixel with the organic light-induced material under the predetermined condition comprises:
forming a first intermediate under ultraviolet light irradiation by decomposing the first pixel define layer;
forming a fourth intermediate by reacting the first intermediate with the hydroxyl group of the organic light-induced material; and
forming a first polymer by polymerizing the fourth intermediate with the unsaturated carbon-carbon double bond of the organic light-induced material; and
the polymer film layer at least comprises the first polymer;
wherein forming the polymer film layer by reacting the first pixel define layer with the organic light-induced material under the predetermined condition comprises:
forming a first intermediate under ultraviolet light irradiation by decomposing the first pixel define layer;
forming a second intermediate under ultraviolet light irradiation by decomposing the first intermediate;
forming a fifth intermediate by reacting the second intermediate with the hydroxyl group of the organic light-induced material; and
forming a second polymer by polymerizing the fifth intermediate with the unsaturated carbon-carbon double bond of the organic light-induced material; and
the polymer film layer at least comprises the second polymer;
wherein the organic light-induced material further comprises a benzophenone functional group.
