| titleOfInvention | Light emitting devices and display panels |
| abstract | The disclosure discloses a light emitting device and a display panel, which relate to the field of display technology and are used to solve the problem of low light extraction efficiency of the light emitting device. Wherein, the light emitting device includes the first electrode, at least two light emitting units and the second electrode stacked in sequence along the first direction. The at least two light emitting units include a first light emitting unit, a second light emitting unit located between the first light emitting unit and the second electrode, and a light emitting unit located between the first light emitting unit and the second light emitting unit. charge generation layer between them. The first light-emitting unit includes a first light-emitting layer, and in the light-emitting device, a plurality of film layers located on a side of the first light-emitting layer away from the first electrode collectively include at least three kinds of metals. The light emitting device and the display panel provided by the present disclosure can reduce the driving voltage of the light emitting device. |
