Abstract
An organic EL element has a substrate, a first electrode, an organic compound layer, and a second electrode. The second electrode has a base layer and a metal layer, and light generated in this organic EL element is transmitted through the second electrode. The base layer is closer to the substrate than the metal layer and is a mixed layer containing lithium, oxygen, and magnesium, whereas the metal layer contains silver and has a thickness in the range of 5.0 to 20 nm, inclusive.
Claims11
An organic electroluminescence (EL) element comprising:
- a substrate;
- a first electrode;
- a second electrode;
- and
- an organic compound layer, wherein:
