Abstract:
1. An organic electroluminescent element comprising: a light-transmitting electrode layer that is provided on a light-transmitting substrate; an electrode layer that forms a pair with the light-transmitting electrode layer; an organic layer that is held between the pair of electrode layers and contains an organic electroluminescent substance; a light-blocking auxiliary electrode that is formed on the light-transmitting electrode layer so as to be in contact with a part of the light-transmitting electrode layer; and an insulating coating film in contact with the auxiliary electrode, that covers the auxiliary electrode, wherein the auxiliary electrode comprises: a low resistivity layer that is formed from a low resistivity material comprising at least one selected from the group consisting of aluminum, aluminum neodymium alloy, aluminum nickel alloy, aluminum silver alloy, aluminum cobalt alloy, aluminum germanium alloy, and silver, that has a lower specific resistance in comparison to the light-transmitting electrode layer; and a coating layer that is provided on the low resistivity layer and is formed from a high melting point material comprising at least one of molybdenum niobium alloy and molybdenum vanadium alloy, that has a higher melting point than the low resistivity material.
