Abstract

An organic light emitting diode (OLED) comprising a substrate, a 1st electrode disposed on the substrate and including at least one lead, a 2nd electrode including at least one lead, an organic light-emitting layer disposed between the 1st electrode and the 2nd electrode, and a conductive layer. At least one of (1) the substrate and the 1st electrode and (2) the 2nd electrode are transparent. The conductive layer is disposed on one of the 1st electrode and the 2nd electrode, and effectively surrounds the light-emitting layer and the other of the 1st electrode and the 2nd electrode.
