Claim 17:
18. A manufacturing method of a display module, the display module according to claim 17, the manufacturing method comprising:
manufacturing the reflective layer on the encapsulation layer of the light-emitting substrate, wherein a surface of the reflective layer configured to be away from the encapsulation layer has microstructures for scattering light, the microstructures include at least one of zigzag structures, wavy structures, columnar structures arranged in an array, conical structures arranged in an array, and spherical structures arranged in an array; or the surface of the reflective layer configured to be away from the encapsulation layer includes at least one curved surface recessed towards a side where the black matrix is located;
manufacturing the black matrix on a side of the reflective layer away from the light-emitting substrate, wherein an orthogonal projection of the reflective layer on the light-emitting substrate is covered by an orthogonal projection of the black matrix on the light-emitting substrate; and
manufacturing the color film layer, wherein the color film layer includes the plurality of filter portions, and the at least a portion of each filter portion is located in the opening of the black matrix.
