Display device, electronic device including the same and method for fabricating the display device

A method for fabricating a display device, the method comprising:

• forming a bank structure including a first bank layer, a second bank layer, and a third bank layer on a substrate including a via layer;
• forming a tip of the third bank layer which protrudes further than a side surface of the second bank layer;
• forming a light-emitting element and an element inorganic layer on the bank structure;
• and
• defining a via hole by removing a portion of the bank structure,
• wherein the via hole penetrates through the first bank layer.

An electronic device comprising:

• a display device including a substrate including a light-emitting area and a non-light-emitting area;
• and
• at least one of a display module, a processor, a memory, and a power module connected to the display device, the display device including:
• a via layer disposed on the substrate and including an organic material;
• a bank structure disposed on the via layer in a portion overlapping the light-emitting area and having an overhang structure;
• an element insulating layer disposed on the bank structure and defining a light-emitting opening;
• and
• a first light-emitting element disposed on the element insulating layer and in contact with the bank structure,
• wherein a via hole penetrating through a first bank layer of the bank structure in a portion overlapping the non-light-emitting area,
• the via hole defines a non-light-emitting opening, and
• the via hole exposes the via layer in a portion overlapping the non-light-emitting opening.
