Display panel and manufacturing method thereof

A method of manufacturing a display panel, wherein the method comprises the following steps:

• step S1, a pixel definition layer is provided on a base substrate, and patterning the pixel definition layer to form at least two first sub-pixel holes, at least two second sub-pixel holes, and at least two third sub-pixels which are sequentially arranged in a row/column direction, and forming a first luminescent material confluence channel communicating with two adjacent first sub-pixel holes and forming a second luminescent material confluence channel communicating with two adjacent second sub-pixel holes along the row/column;
• step S2, sequentially arranging a plurality of nozzles in the row/column direction with the at least two first sub-pixel holes, the at least two second sub-pixel holes, and the at least two third sub-pixel holes, and forming a luminescent material in a row/column linear manner including forming a first luminescent material in the at least two first sub-pixel holes and the first luminescent material confluence channel, forming a second luminescent material in the at least two second sub-pixel holes and the second luminescent material confluence channel, and forming a third luminescent material in the at least two third sub-pixel holes;
• step S3:
• forming a cathode layer on the luminescent material;
• and
• step S4, forming a thin-film encapsulation layer on the cathode layer.
