Display panel, electronic device including the same, and method for manufacturing display panel

An electronic device comprising:

• a display panel that is capable of displaying an image;
• an electronic module disposed beneath the display panel;
• and
• a casing accommodating the display panel and the electronic module, wherein
• the display panel includes:
• a circuit layer disposed on a base substrate;
• a first electrode disposed in a first region on the circuit layer;
• an auxiliary electrode disposed in a second region on the circuit layer and spaced apart from the first electrode;
• a second electrode disposed on the first electrode and the auxiliary electrode;
• a plurality of organic layers disposed between the first electrode and the second electrode;
• and
• at least one charge generation layer disposed between the plurality of organic layers, wherein
• each organic layer of the plurality of organic layers and the charge generation layer includes an opening region directly over the auxiliary electrode,
• the second electrode is electrically connected to the auxiliary electrode through each opening region of the plurality of organic layers and the charge generation layer,
• an organic layer disposed adjacent to the second electrode among the plurality of organic layers includes a protrusion adjacent to the opening region of the organic layer disposed adjacent to the second electrode, and
• at least another organic layer besides the organic layer disposed adjacent to the second electrode includes no protrusion adjacent to the opening region.

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

• providing a target substrate including:
• a pixel electrode;
• and
• an auxiliary electrode, the auxiliary electrode and the pixel electrode being disposed on a same layer;
• forming a light emitting stack including a charge generation layer on the pixel electrode and the auxiliary electrode;
• forming an opening region penetrating the light emitting stack and forming a protrusion adjacent to the opening region by irradiating a laser onto the light emitting stack overlapping the auxiliary electrode in a plan view;
• and
• forming a common electrode on the light emitting stack,
• wherein the common electrode is electrically connected to the auxiliary electrode through the opening region.
