Abstract
An organic EL display wherein electric connection between the electron injecting electrode layer and the electrode layer is improved, which is less likely to suffer from poor connection, and which exhibits low connection resistance is realized. A method for producing such an organic EL display is also realized. Such an organic EL display has an electrode structure which connects at least a terminal and an electron injecting electrode, and the electrode structure comprises an underlying layer,as a lower layer comprising a metal having low susceptibility to surface oxide layer formation, and an electrode layer,as an upper layer comprising a metal which has a susceptibility to surface oxide layer formation higher than that of the underlying layer,. The underlying layer,and the electron injecting electrode layer,are in direct contact with each other at least in some parts in the region where the electrode layer,is connected to said electron injecting layer
