    摘要: The present application provides a light-emitting device and a display device, which relates to the field of display technology, including: a substrate; a first electrode and a second electrode located on the substrate: a light-emitting layer located between the first electrode and the second electrode; and a capping layer located on a side of the second electrode away from the light-emitting layer, wherein the capping layer includes a compound of aromatic amines, and a structure of the compound of aromatic amines includes one of following two structures 1:




    and the capping layer made of the compound of aromatic amines has a high refractive index and high stability, such that when the light-emitting device is used, the light-outlet efficiency of the device may be improved, and the service life of the device may be prolonged.
