Display device and method of manufacturing the same

A display device comprising:

• a lower substrate having a display area and a pad area;
• a display structure disposed in the display area of the lower substrate;
• an upper substrate disposed on the display structure in the display area, and facing the lower substrate;
• pad electrodes disposed in the pad area of the lower substrate and spaced apart from each other in a first direction parallel to a top surface of the lower substrate;
• a conductive film member including conductive balls disposed on the pad electrodes, the conductive film member having a first area overlapping the pad electrodes and a second area not overlapping the pad electrodes;
• and
• a film package disposed on the conductive film member and including bump electrodes overlapping the first area of the conductive film member,
• wherein:
• the shape of the conductive balls disposed in the first area is different from those disposed in the second area;
• the conductive balls are arranged in the first direction and a second direction orthogonal to the first direction;
• and
• each of the conductive balls do not overlap one another in a third direction perpendicular to the first and second directions.
