Abstract: Some embodiments provide a full-color display module and display device. The full-color display module includes at least two light-emitting layers. Any one of the at least two light-emitting layers includes a substrate and a plurality of light-emitting portions encapsulated on the substrate. A type of any one of the plurality of light-emitting portions is one of a red light-emitting portion, a green light-emitting portion, and a blue light-emitting portion. The at least two light-emitting layers are successively laminated in a laminating direction and form a plurality of pixel points. Any one of the plurality of pixel points is a surrounding area on the full-color display module, which is surrounded by a surrounding curved surface. The surrounding area of the any one of the plurality of pixel points includes at least one red light-emitting portion, at least one green light-emitting portion, and at least one blue light-emitting portion.
