Display module, method for manufacturing display module and display device

The invention discloses a display module, a method for manufacturing the display module and a display device. The display module comprises: a display panel; a panel back film assembly located on the back face of the display panel, wherein at least one first through hole penetrating through the panel back film assembly is formed in the panel back film assembly; a metal layer located on the surface, away from the display panel, of the panel back film assembly, wherein the metal layer is grounded; a conductive filling piece, wherein the first through hole is filled with the conductive filling piece, and the conductive filling piece is in contact with the metal layer. Therefore, the static electricity generated by the display panel can be dredged through the conductive filling piece, and when the static electricity is generated in the use process of the display module, the static electricity can be quickly dissipated along the path of the conductive filling piece, so that the adverse effect of the static electric
