Claim 13:
14. The method of manufacturing the light-emitting substrate according to claim 13, wherein the plurality of light-emitting devices include N types of light-emitting devices with different emission colors, and N is an integer greater than or equal to 2; and
forming the plurality of light-emitting devices on the base includes:
forming a plurality of first electrodes on the base;
forming a film having electron transport function on the base on which the plurality of first electrodes have been formed;
forming an I-th mask on the base on which the film having the electron transport function has been formed, the I-th mask exposing portions of the film having the electron transport function located in regions where an I-th type of light-emitting devices are located, and covering a portion of the film having the electron transport function located in a region except the regions where the I-th type of light-emitting devices are located;
bombarding the portions of the film having the electron transport function located in the regions where the I-th type of light-emitting devices are located for an I-th duration by using plasma from a side of the film having the electron transport function away from the base, so that oxygen vacancies are formed in the portions of the film having the electron transport function located in the regions where the I-th type of light-emitting devices are located to obtain I-th ETLs;
forming I-th EMLs on a side of the I-th ETLs away from the base; and
removing the I-th mask; wherein
I is greater than or equal to 1, and less than or equal to N.
