Abstract

The invention discloses a light emitting device and a display panel. The light emitting device comprises a first electrode, a second electrode, a light-emitting layer arranged between the first electrode and the second electrode, including a first host material and a guest material, and having a side facing the first electrode and a side facing the second electrode, and an auxiliary light-emittinglayer arranged on at least one side of the light-emitting layer; and the auxiliary light-emitting layer material and the first host material are light-emitting host materials used for light-emittingdevices of the same color. The light emitting efficiency of the light emitting device can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light emitting device and a display panel. Background technique [0002] Organic Light-Emitting Diode (OLED) is an electroluminescent device based on organic materials. Its basic structure includes an anode, a cathode and a light-emitting layer. When a voltage is applied to the anode and the cathode, the effect of the electric field Next, the holes generated by the anode and the electrons generated by the cathode migrate to the light-emitting layer. When the two meet in the light-emitting layer, they combine to generate excitons, which excite the light-emitting molecules to generate visible light. [0003] Due to the different transport rates of electrons and holes in organic materials, the number of electrons and holes in the light-emitting layer is not equal, and the recombination centers of electrons and holes will shift to the electrode side; The dismantling of the large ...
