Abstract: A manufacturing method of a display device includes forming light emitting components on a first substrate, the light emitting components include a first side and a second side, and the second side is away from the first substrate; forming a circuit layer on the first substrate and on the second side of the light emitting components; forming a first protective layer on the circuit layer and forming an insulating layer on the first protective layer; removing the first substrate after forming a second substrate on the insulating layer; forming a black matrix layer on the first side of the light emitting components, and the black matrix layer includes openings; forming light conversion layers in the openings of the black matrix layer; forming a second protective layer on the black matrix layer and the light conversion layers; and forming a third substrate on the second protective layer.
