Provided is an organic electroluminescent device. The electroluminescent device includes an anode, a cathode and an organic layer disposed between the anode and the cathode, where the organic layer includes a first compound having a structure of H-L-Eand a second compound having a structure of H-L-E. The electroluminescent device containing a novel material combination has a low driving voltage, high device efficiency and a significantly improved device lifetime, which greatly improves the overall performance of the device. Further provided are an electronic equipment including the preceding electroluminescent device and use of the electroluminescent device in an electronic element module, a display apparatus or a lighting apparatus.

Organic electroluminescent device

Provided is an organic electroluminescent device. The organic electroluminescent device comprises a first electrode, a second electrode, and at least two light emitting units disposed between the first electrode and the second electrode, wherein the light emitting units each comprises at least one light emitting layer, and a connection layer of a specific structure is further disposed between adjacent two light emitting units. By using a connection layer of a specific structure, the organic light-emitting device reduces the device voltage, prolongs life time of the device, and improves the device performance.
