Display panel and manufacturing method thereof and display device including display panel

A display device, comprising:

• a display panel, wherein the display panel comprises:
• a substrate;
• a thin-film transistor arranged on the substrate;
• an electroluminescent diode arranged on the thin-film transistor, comprising a bottom electrode, a light emitting layer, and a top electrode;
• and
• a thin-film encapsulation layer covering the electroluminescent diode;
• wherein
• the display panel further comprises an auxiliary electrode, and the auxiliary electrode is electrically connected to a lead wire of the top electrode of the electroluminescent diode by penetrating through a via hole of the thin-film encapsulation layer.

A method for manufacturing a display panel, comprising:

• forming a thin-film transistor on a substrate;
• forming an electroluminescent diode on the thin-film transistor, the electroluminescent diode comprising a bottom electrode, a light emitting layer, and a top electrode;
• forming a thin-film encapsulation layer to cover the electroluminescent diode;
• and
• forming an auxiliary electrode, the auxiliary electrode being electrically connected to a lead wire of the top electrode of the electroluminescent diode by penetrating through a via hole of the thin-film encapsulation layer.
