Abstract: Provided are a light-emitting element and a display device containing the light-emitting element. The light-emitting element comprises an anode, a cathode opposite to the anode, and a plurality of organic layers placed between the anode and the cathode; at least three of the plurality of organic layers each independently contain a compound having a spirobifluorene structure; or at least two of the plurality of organic layers each contain the compound having a spirobifluorene structure and together contain at least three types of the compound having a spirobifluorene structure. By providing the organic layers with the compound having a spirobifluorene structure, the HOMO or LUMO energy level difference for hole or electron transport between different organic layers can be reduced due to the spirobifluorene compounds having the same main ring structure, which facilitates injection of electrons and/or holes, improving the luminous efficiency and lowering the turn on voltage.
