| titleOfInvention | An organic electroluminescent element |
| abstract | The invention provides an organic electroluminescence element, which belongs to the technical field of organic electroluminescence. The organic electroluminescence element of the present invention includes a substrate, an anode, an organic layer, and a cathode. The organic layer includes a hole transport layer, and the hole transport layer includes a first hole transport layer and a second hole transport layer. The first hole transport layer The layer contains amine derivatives containing polycycloalkyl groups, and the second hole transport layer contains triarylamine derivatives, both of which are used together as hole transport layer materials, which can not only effectively improve the luminous efficiency and use of organic electroluminescent elements It is also possible to reduce the driving voltage of the organic electroluminescence element. The organic electroluminescence element prepared by the invention improves device characteristics, effectively increases its luminous efficiency and service life, and at the same time greatly reduces the driving voltage of the element, and has good application effect and industrialization prospect. |
