Abstract
The present invention relates to an organic electroluminescent element and a display device, in which, on a substrate 1, at least an anode 2, an organic layer 3 having a luminescent layer 8, an electron injecting layer 4 and a cathode 5 are laminated in this order or in the reverse order In the organic electroluminescent element, an outer peripheral portion of the cathode 5 is positioned inside an outer peripheral portion of the electron injecting layer 4.
Claims20
An organic electroluminescent element which comprises, on a substrate, at least an anode, an organic layer having a luminescent layer, an electron injecting layer and a cathode laminated in this order or in the reverse order, wherein an outer peripheral portion of the cathode is positioned inside an outer peripheral portion of the electron injecting layer.
An organic electroluminescent element which includes, on a substrate, at least an anode, an organic layer having a luminescent layer, an electron injecting layer and a cathode laminated in this order or in the reverse order, wherein an outer peripheral portion of the cathode other than an area where a lead-out electrode is formed is positioned inside an outer peripheral portion of the electron injecting layer.
A method for producing an organic electroluminescent element, wherein the organic electroluminescent element comprises on a substrate, at least an anode, an organic layer having a luminescent layer, an electron injecting layer and a cathode laminated in this order or in the reverse order, wherein a mask for deposition used for forming the electron injecting layer has an opening area different from an opening area of a mask for deposition used for forming the cathode.
