Organic light emitting display device and method for manufacturing the same

An organic light emitting display device comprising:

• 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;
• a lower touch pad unit formed in the non-display area, the lower touch pad unit adjacent to the exposed area on the lower substrate;
• an upper substrate opposite to a remaining area excluding the exposed area of the lower substrate;
• an upper touch pad unit on the upper substrate, the upper touch pad unit corresponding to the lower touch pad unit;
• a first connection electrode in direct contact with the lower touch pad unit;
• a second connection electrode opposite to the first connection electrode and in direct contact with the upper touch pad unit;
• a self-assembly contact member disposed between the first connection electrode and the second connection electrode, the self-assembly contact member electrically connecting together the first connection electrode and the second connection electrode;
• and
• a sealing member in the non-display area and encloses side surfaces of the first connection electrode, the self-assembly contact member, and the second connection electrode.
