Display panel and manufacturing method of the same

A method for manufacturing a display panel, the method comprising:

• providing a preliminary display panel comprising a base layer, a first anode disposed above the base layer, a pixel defining layer disposed above the base layer and including a first light-emitting opening and exposing a portion of the first anode, and a conductive partition disposed on the pixel defining layer and including a first partition opening and corresponding to the first light-emitting opening;
• depositing a first organic material to form a first light-emitting pattern at least partially disposed in the first light-emitting opening and the first partition opening and a first dummy layer spaced apart from the first light-emitting pattern and disposed on the conductive partition;
• depositing a first conductive material to form a first cathode at least partially disposed in the first partition opening;
• forming a first mask pattern overlapping the first light-emitting opening in a plan view and comprising a second conductive material, on the conductive partition;
• patterning the first dummy layer by the first mask pattern to form a first dummy pattern from the first dummy layer;
• and
• depositing the second conductive material to form a first conductive layer from the first mask pattern,
• wherein in the depositing of the second conductive material, the first conductive layer covers an outer side surface of the first dummy pattern.
