Abstract:
A device capable of having an easy production process and achieving a long lifetime. The device has a substrate, two or more electrodes facing each other disposed on the substrate and a positive hole injection transport layer disposed between two electrodes among the two or more electrodes. The positive hole injection transport layer has a transition metal-containing nanoparticle containing at least a transition metal compound including a transition metal oxide, a transition metal and a protecting agent, or at least the transition metal compound including the transition metal oxide, and the protecting agent.
