| Zusammenfassung: | The invention discloses a light emitting device and a display panel. The light emitting device comprises a first electrode, a light emitting layer and a second electrode which are arranged in a stacked mode, at least one service life improving functional layer is further included, wherein the service life improving function layer is arranged between the light emitting layer and the first electrode, and/or the service life improving function layer is arranged between the light emitting layer and the second electrode, the service life improving function layer comprises a carrier barrier layer and at least one exciton barrier layer, the exciton barrier layer is arranged on one side, adjacent to the light emitting layer, of the carrier barrier layer, and the triplet state energy level of the exciton barrier layer is greater than the triplet state energy level of the light emitting layer. The light emitting device is advantaged in that the service life of the light emitting device is betterprolonged and light emit |
