| titleOfInvention | An organic electroluminescent device containing a composite electron blocking layer |
| abstract | The invention discloses an organic electroluminescence device, which is provided with a substrate, a first electrode, an organic functional material layer and a second electrode in sequence from bottom to top, and the organic functional material layer includes: a hole transport region, located in the above the first electrode; a light-emitting layer, located on the hole transport region, which includes a host material and a guest material; an electron transport region, located above the light-emitting layer; the hole transport region sequentially includes from bottom to top A hole injection layer, a hole transport layer and an electron blocking layer, the electron blocking layer includes a first organic material and a second organic material. Compared with the use of organic materials alone as electron blocking layer materials, the driving voltage of the device of the present invention is significantly reduced, and both the luminous efficiency (ie, current efficiency) and lifetime are significantly improved. |
