Claim 12:
13. The manufacturing method according to claim 11, further comprising: forming a second light-emitting functional portion on the base substrate by using an evaporation process, wherein
forming the second light-emitting functional portion comprises: aligning the base substrate with a second FMM, wherein the second FMM comprises a second rib and a second through hole enclosed by a second side surface of the second rib, and the second rib has a second surface and a second ridged edge, the second surface of the second rib contacts the PS during the evaporation process, and the second ridged edge is located between and connects the second side surface and the second surface; in forming the second light-emitting functional portion, an orthographic projection of a portion of a second ridged edge of the second rib on the base substrate falls within the orthographic projection of the first recess on the base substrate;
in forming the first light-emitting functional portion, one of the adjacent protrusions supports the first rib of the first FMM; and in forming the second light-emitting functional portion, the other one of the adjacent protrusions supports the second rib of the second FMM.
