Display panel, method for manufacturing the same, and display device comprising the same

A method for preparing a display panel, comprising:

• forming an array substrate, wherein:
• the array substrate comprises a first signal line, a first auxiliary line, and a second auxiliary line, which are disposed in a display region of the display panel;
• the first auxiliary line is configured to transmit signals to the first signal line, and comprises at least one first auxiliary line segment;
• the second auxiliary line is insulated from the first auxiliary line, and comprises at least one second auxiliary line segment;
• and
• forming a plurality of light-emitting elements at a side of the array substrate, wherein:
• each light-emitting element of the plurality of light-emitting elements comprises an anode, a light-emitting functional layer, and a cathode, which are arranged in the above-listed sequence along a direction pointing away from the array substrate;
• and
• the cathode is electrically connected to the at least one second auxiliary line segment in the display region.

A display device, comprising a display panel, comprising:

• an array substrate, wherein:

• the first auxiliary line is configured to transmit signals to the first signal line, and comprises at least one first auxiliary line segment;
• the second auxiliary line is insulated from the first auxiliary line, and comprises at least one first auxiliary line segment;
• and
• each of the at least one second auxiliary line segment is disposed in a same layer as a corresponding one of the at least one first auxiliary line segment;
• a plurality of light-emitting elements disposed at a side of the array substrate, wherein:
• each light-emitting element of the plurality of light-emitting elements comprises an anode, a light-emitting functional layer, and a cathode, which are arranged in the above-listed sequence along a direction pointing away from the array substrate;
• and
• the cathode is electrically connected to the at least one second auxiliary line segment in the display region.
