<P>PROBLEM TO BE SOLVED: To provide a superior organic EL display device which can prevent current from flowing from a second electrode to a connected electrode when a second organic compound layer emits light, causing a first organic compound layer to emit light, and is free of color drift and luminance degradation. <P>SOLUTION: A substrate 11 has a first electrode 12, a first organic compound layer 14, a second electrode 15, a second organic compound layer 16, and a third electrode 17 laminated thereon and includes a connecting electrode 12A to connect the third electrode 17 to a drive circuit. An electron injection layer EIL or a hole injection layer HIL adjoining the second electrode 15 is formed on the first organic compound layer 14 and/or the second organic compound layer 16. There is no partial presence of the first organic compound layer 14 and the second organic compound layer 16, at least of the electron injection layer EIL or the hole injection layer HIL, in a route where a leak path from the second electrode 15 to the connecting electrode 12A can be formed and any portion on the surface of the connecting electrode 12A. <P>COPYRIGHT: (C)2012,JPO&INPIT |
