Abstract
An electrostatic discharge device and an organic electro-luminescence display device having the same are provided. The organic electro-luminescence display device includes an electrostatic discharge device including a metal pattern having an island shape on a substrate, an insulating layer on the metal pattern, a semiconductor pattern on the insulating layer, the semiconductor pattern corresponding to the metal pattern, a first electrode overlapping one end of the semiconductor pattern, and a second electrode overlapping the other end of the semiconductor pattern, and spaced from the first electrode, thereby preventing a current leakage, a signal distortion and a signal cross-talk to improve the reliability.
