摘要
The present invention is to provide a device capable of having an easy production process and achieving a long lifetime. A device comprising 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, wherein the positive hole injection transport layer contains a transition metal compound-containing nanoparticle comprising a transition metal compound containing one or more kinds selected from the group consisting of a transition metal carbide oxide, transition metal nitride oxide and transition metal sulfide oxide, wherein a protecting agent having a linking group and a hydrophobic organic group is connected to the transition metal compound by the linking group.
