Claim 11:
12. A manufacturing method of an organic light emitting display device, comprising:
preparing a lower substrate including a plurality of sub-pixels, the lower substrate having a display area, a non-display area enclosing the display area, and an exposed area extending from one side of the non-display area;
forming a lower touch pad unit in the non-display area, the lower touch pad unit adjacent to the exposed area;
forming a first connection pad unit and a second connection pad unit in the exposed area of the lower substrate;
forming an upper touch pad unit corresponding to the lower touch pad unit, a touch sensor corresponding to the display area, and a touch line connecting the touch sensor and the upper touch pad unit, on an upper substrate;
patterning a first connection electrode on the lower touch pad unit that is in contact with the lower touch pad unit and patterning a second connection electrode on the upper touch pad unit that is in contact with the upper touch pad unit;
applying a self-assembly composition including solder particles on the lower touch pad unit;
disposing and attaching the lower substrate and the upper substrate such that the first connection electrode and the second connection electrode are opposite to each other; and
forming a self-assembly contact member between the lower touch pad unit and the upper touch pad unit by heating the self-assembly composition,
wherein the first connection pad unit is connected to a thin film transistor formed in the display area of the lower substrate, and the second connection pad unit is connected to the lower touch pad unit.
