Display device and manufacturing method of the same

A display device comprising:

• an external bank disposed on a substrate defining an emission area;
• a first light emitting element and a second light emitting element spaced apart from each other, each disposed on the substrate in the emission area and including a first end having a first polarity and a second end having a second polarity;
• a first connection electrode disposed on the substrate and electrically contacting the first end of the first light emitting element;
• a second connection electrode disposed on the substrate, spaced apart from the first connection electrode, and electrically contacting the first end of the second light emitting element;
• a first insulating layer disposed on the first connection electrode and the second connection electrode and exposing the second end of the first light emitting element and the second end of the second light emitting element;
• a third connection electrode disposed on the first insulating layer, electrically contacting the second end of the first light emitting element, and having a width greater than a width of the first connection electrode in a direction;
• and
• a fourth connection electrode disposed on the first insulating layer, spaced apart from the third connection electrode, electrically contacting the second end of the second light emitting element, and having a width greater than a width of the second connection electrode in the direction.
