Classification: CPC H | IPC H

Claim 15:
16. The method of manufacturing the light-emitting substrate according to claim 14, wherein
forming the I-th mask on the base on which the film having the electron transport function has been formed includes:
sequentially forming a sacrificial film and a photoresist film on the base on which the film having the electron transport function has been formed;
removing portions of the photoresist film covering the regions where the I-th type of light-emitting devices are located through exposure and development to obtain a photoresist layer;
bombarding the base on which the photoresist layer has been formed by using plasma, so as to remove portions of the sacrificial film covering the regions where the I-th type of light-emitting devices are located, and to obtain the I-th mask including the photoresist layer and a sacrificial layer;
bombarding the portions of the films having the electron transport function located in the regions where the I-th type of light-emitting devices are located for the I-th duration by using plasma from the side of the film having the electron transport function away from the base, includes: continuously bombarding the base for the I-th duration after removing the portions of the sacrificial film covering the regions where the I-th type of light-emitting devices are located, so as to form the I-th ETLs in the regions where the I-th type of light-emitting devices are located.
