A manufacturing method of a light-emitting layer comprises: S1, providing a substrate (101); S2, performing evaporation on the substrate (101) to obtain a green light-emitting layer (104); S3, employing UV radiation to destruct portions of the green light-emitting layer (104) at the left and middle regions; S4, performing evaporation on the substrate (101) to obtain a red light-emitting layer (105); S5, employing UV radiation to destruct a portion of the red light-emitting layer (105) at the leftmost region; S6, performing evaporation on the substrate (101) to obtain a blue light-emitting layer (106); and S7, performing evaporation on the substrate (101) to obtain an electron transport layer (107), an electron injection layer (108) and a cathode (109), and performing encapsulation. L'invention concerne un procédé de fabrication d'une couche électroluminescente consistant à : S1, fournir un substrat (101) ; S2, réaliser une évaporation sur le substrat (101) pour obtenir une couche électroluminescente verte (10
