Abstract
The present invention provides an organic electroluminescence device capable of having not only a device lifetime comparable to that of an existing organic electroluminescence device but also a small thickness of smaller than 10 μm and excellent flexibility. The present invention relates to an organic electroluminescence device having a structure including: an anode; a cathode on a substrate; and a laminate of multiple layers between the anode and the cathode, the device having a thickness of smaller than 10 μm.
Claims16
An organic electroluminescence device having a structure comprising:
- an anode;
- a cathode on a substrate;
- and
- a laminate of multiple layers between the anode and the cathode, and
- a laminate structure including a metal oxide layer, an elemental metal layer, a layer of a metal compound having a surface energy of 60 dyne/cm or higher, and an organic compound layer stacked in the stated order from an anode-side end of the laminate structure,
- the device having a thickness of smaller than 10 μm.
