Display device and method of manufacturing the same

A display device comprising:

• a first pixel electrode disposed on a substrate in a first emission area;
• a second pixel electrode disposed on the same layer as the first pixel electrode in a second emission area;
• an insulating layer covering edges of each of the first and second pixel electrodes;
• a first light emitting layer disposed on the first pixel electrode and the insulating layer;
• a first common electrode disposed on the first light emitting layer;
• a second light emitting layer disposed on the second pixel electrode and the insulating layer;
• a second common electrode disposed on the second light emitting layer;
• a conductive layer disposed on the insulating layer to surround each of the first and second emission areas and electrically connect the first and second common electrodes;
• a first bank disposed on the conductive layer;
• a second bank disposed on the first bank and including tips protruding from side surfaces of the first bank toward each of the first and second emission areas;
• a third bank disposed on the second bank;
• and
• a fourth bank disposed on the third bank and including tips protruding from side surfaces of the third bank toward each of the first and second emission areas.

A method of manufacturing a display device, the method comprising:

• forming pixel electrodes and sacrificial layers on a substrate, the pixel electrodes including a first pixel electrode which overlaps a first emission area and a second pixel electrode which overlaps a second emission area;
• sequentially stacking an insulating layer, a conductive layer, a first bank, a second bank, a third bank, and a fourth bank on the pixel electrodes;
• forming tips of the second bank which protrude from side surfaces of the first bank by etching the fourth bank, the third bank, the second bank, the first bank, and the conductive layer;
• exposing the first and second pixel electrodes by etching the insulating layer and the sacrificial layer;
• forming a first light emitting layer on the first pixel electrode and a first organic pattern on the fourth bank;
• forming a first common electrode on the first light emitting layer and a first electrode pattern on the first organic pattern on the fourth bank;
• forming a capping layer on the first common electrode and a first capping pattern on the first electrode pattern on the fourth bank;
• and
• forming a first inorganic layer which covers an upper surface of the capping layer, the side surfaces of the first bank, lower and side surfaces of the tips of the second bank, side surfaces of the third and fourth banks, side surfaces of the first organic pattern, side surfaces of the first electrode pattern, and upper and side surfaces of the first capping pattern.
