1. A manufacturing method of a flexible double-sided display screen, comprising following steps:
providing two display devices, wherein each of the two display devices comprises a first support plate, a flexible substrate disposed on the first support plate, a light-emitting device layer disposed on the flexible substrate, and an encapsulation layer disposed on the flexible substrate and the light-emitting device layer, the light-emitting device layer comprises a plurality of sub light-emitting devices disposed at intervals, and a plurality of light-shielding layers are disposed between the flexible substrate and the light-emitting device layer, the plurality of the light-shielding layers are disposed at intervals and correspond one-to-one to the plurality of the sub light-emitting devices, and an orthogonal projection of each of the sub light-emitting devices on the flexible substrate is located within an orthogonal projection of a corresponding one of the light-shielding layers on the flexible substrate;
attaching two second support plates onto encapsulation layers of the two display devices, respectively;
stripping off first support plates of the two display devices;
attaching flexible substrates of the two display devices together; and
stripping off the two second support plates of the two display devices.
