Abstract: The present disclosure relates to an anisotropic conductive film, a display device and a reworking method thereof. The anisotropic conductive film comprises: a first resin layer having positively photosensitive characteristics and conductive particles distributed in the first resin layer. Since the first resin layer has positively photosensitive characteristics, it can be decomposed after the exposure process. In this case, when failures occur in the binding of the display panel with the external circuit by the anisotropic conductive film, the first resin layer in the anisotropic conductive film can be decomposed by performing an exposure process on the anisotropic conductive film, so as to separate the external circuit from the display panel for reworking of the display panel. In this way, no heating process is needed, which not only simplifies the reworking procedure, but also is suitable for the reworking of a flexible display panel.
