A hybrid light emitting device, a display panel, and a display device are disclosed. The hybrid light emitting device comprises a first electrode, a light emitting material composite layer, a hybrid connecting composite layer, a first light emitting layer, and a second electrode which are stacked in this order. The first electrode and second electrode are configured to provide a first carrier and a second carrier during operation, respectively. The hybrid connecting composite layer comprises at least two hybrid connecting layers. In a direction from the first electrode to the second electrode, the at least two hybrid connecting layers increase in term of the first carrier mobility and decrease in term of the second carrier mobility.
