Classification: CPC G | IPC G

Claim 0:
1. A color film structure, comprising:
a black matrix having a plurality of openings;
a color film layer including a plurality of filter portions, at least a portion of each filter portion being located in an opening of the black matrix; and
a reflective layer located on a side of the black matrix configured to be proximate to a light-emitting substrate, an orthogonal projection of the reflective layer on a plane where the black matrix is located being covered by the black matrix; the reflective layer being configured to reflect at least a part of light emitted from the light-emitting substrate to the black matrix back to the light-emitting substrate, so that at least a part of the light reflected back to the light-emitting substrate is emitted through the color film layer, wherein
a surface of the reflective layer configured to be away from the light-emitting substrate 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 light-emitting substrate includes at least one curved surface recessed towards a side where the black matrix is located.
