Abstract
The present disclosure provides a display panel and a manufacturing method of the display panel. The display panel includes an array substrate, a first electrode, a pixel definition layer, an organic functional layer, a second electrode, a covering layer, and an auxiliary electrode. By arranging an auxiliary cathode in a non-display area and using a parallel connection of the auxiliary cathode and a cathode, a cathode resistance of devices is reduced to relieve an IR-drop phenomenon and improve a brightness uniformity of the panel. The present disclosure provides the manufacturing method of the display panel. An organic material can be patterned to form the covering layer without using a fine mask, and a metal material can be patterned to form the auxiliary electrode by utilizing characteristics of self-assembled materials, thereby reducing production costs.
