Patent ID: 7821198

Claim:
An OLED display device comprising: a first substrate having formed thereon a sub-pixel driving array; a second substrate having formed thereon an OLED array; a sealant bonding the first and second substrates to each other; and an anisotropic conductive film deformed when bonding the first and second substrates to each other so as to electrically connect the sub-pixel driving array and the OLED array to each other, wherein the anisotropic conductive film is formed on the sub-pixel driving array and includes resin and conductive balls having the deformable property, wherein the OLED display device further comprises an organic insulation layer formed between the sub-pixel driving array and the anisotropic film, wherein the organic insulation layer has contact holes to expose predetermined portions of electrodes on the first substrate, wherein the conductive balls are inserted into the contact holes and each of the conductive balls is smaller than each of the contact holes.
