Organic light emitting display and method of manufacturing the same
An organic light emitting display and a method of manufacturing the same. The light emitting display includes a substrate having a pixel region and a non-pixel region; an organic light emitting diode (OLED) in the pixel region and including a first electrode, an organic thin layer, and a second electrode; a driving circuit unit in the non-pixel region and for driving the OLED; a shielding layer in the non-pixel region and on the driving circuit unit, the shielding layer being electrically coupled to a ground power source; and an insulating layer interposed between the driving circuit unit and the shielding layer. The shielding layer effectively protects the driving circuit unit in the non-pixel region form electrostatic discharge (ESD). Also, the light emitting display may include a guard ring at an edge portion of the non-pixel region and electrically coupled to the shielding layer to further protect the driving circuit from ESD.
