Abstract: The present application provides a crosslinking agent, a light-emitting device and a display panel, and the preparation methods therefor. The crosslinking agent includes an electroactive group and a crosslinking group, wherein the electroactive group and the crosslinking group are bonded, and the crosslinking group is located on at least a portion of the periphery of the electroactive group. For the crosslinking agent provided according to an embodiment of the present application, the electroactive group is conductive, which facilitates the transport of electrons or holes. Thus, the application of the crosslinking agent to a light-emitting functional layer of a light-emitting device is beneficial for improving the electron/hole transport performance of the light-emitting functional layer and lowering the voltage of the light-emitting device, resulting in reduced power consumption of the light-emitting device.
