An organic electro-luminescence display device includes a thin film transistor on a first substrate, where the thin film transistor has a drain region and a common electrode connected to the drain region. An organic electro-luminescence diode resides on a second substrate, where the organic electro-luminescence diode includes a spacer covered with a diode electrode. First and second sealant materials reside at a periphery of the first and second substrates, where the first sealant material surrounds the thin film transistor and the organic electro-luminescence diode, and the second sealant material surrounds an outer perimeter of the first sealant material. The first and second substrates are bonded together, such that the common electrode of the thin film transistor contacts the diode electrode of the organic electro-luminescence diode. The bonding process is carried out by sequentially sealing the first sealant material and the second sealant material.
