Abstract

Provided is a flexible circuit board (10), the flexible circuit board (10) comprising a main body sub-circuit board (100) and a bridge sub-circuit board (200); the main body sub-circuit board (100) comprises a first substrate, as well as a first bridge end (101), a second bridge end (102), a first wire portion (103), and a second wire portion (104) disposed on the first substrate, the first wire portion (103) and the second wire portion (104) being mutually separated and being respectively and electrically connected to the first bridge end (101) and the second bridge end (102); the bridge sub-circuit board (200) comprises a second substrate, as well as a third bridge end (201), a fourth bridge end (202), and a third wire portion (203) used for first functional wiring, all disposed on the second substrate, the third bridge end (201) and the fourth bridge end (202) being electrically connected by means of the third wire portion (203); the first substrate and the second substrate are not in direct contact, and the bridge sub-circuit board (200) is configured to be separately and electrically connected to the first bridge end (101) and the second bridge end (102) by means of the third bridge end (201) and the fourth bridge end (202), and is thereby installed onto the main body sub-circuit board (100). Also provided are a display device, a circuit board structure, and a manufacturing method for the flexible circuit board (10).
