Patent ID: 8319418

Claim:
An organic electro-luminescence display device comprising: a thin film transistor array unit formed on a front surface of a lower substrate, the thin film transistor array unit having gate lines and data lines; a pad portion extended from the thin film transistor array unit, the pad portion including gate pads extended from the gate lines and data pads extended from the data lines; an organic EL array unit on the thin film transistor array unit having a matrix of organic EL cells, each cell having an anode, a cathode and an organic EL layer between the anode and the cathode; and a protective member for protecting the organic EL array unit and the thin film transistor array unit and exposing the pad portion to an outside, wherein the lower substrate has a thickness of a first region overlapped with the pad portion thicker than a thickness of a second region overlapped with the thin film transistor array unit.
