Abstract
The present invention provides a light-transmitting electrode in which metal lines made of a metal with the same or superior electric conductivity to a material for the electrode are arranged linearly on the upper surface, lower surface or both surface of the electrode in the direction away from the connection part between the electrode and an electrode pad. Also, the present invention provides an electrode with a structure in which different electrically conductive compounds are alternately layered. The electrode of the present invention is excellent in transparency and electric conductivity. Also, the present invention provides organic light-emitting devices comprising the electrode.
