18. A display panel, being manufactured by a manufacturing method of the display panel, wherein the method comprises:
providing a substrate;
disposing a plurality of pixel electrode layers and a plurality of electrode layers on the substrate, wherein the pixel electrode layers and the electrode layers are insulated from each other;
disposing a pixel definition layer on one side of the pixel electrode layers away from the substrate;
forming a plurality of openings corresponding to the pixel electrode layers on the pixel definition layer, wherein each of the openings corresponds to each of the pixel electrode layers;
forming electric fields between the pixel electrode layers or between the pixel electrode layers and the electrode layers,
wherein the forming of the electric fields between the pixel electrode layers comprises: electrifying the pixel electrode layers to generate voltage differences between the pixel electrode layers and then forming the electric fields between the pixel electrode layers,
wherein the forming of the electric fields between the pixel electrode layers and the electrode layers comprises: electrifying the pixel electrode layers and the electrode layers to generate voltage differences between the pixel electrode layers and the electrode layers, and then forming the electric fields between the pixel electrode layers and the electrode layers; and
ink-jet printing a plurality of light-emitting functional layers into the openings under the electric fields.
