Disclosed are a display module and a method for manufacturing the same, and a display device. The display module includes: a display panel, a heat dissipation layer, a heat conduction assembly, and a driving chip, wherein the display panel includes a first part and a second part opposite to each other, and a bending part connecting the first part and the second part; the heat dissipation layer is disposed on a side, proximal to the second part, of the first part; the heat conduction assembly is disposed between the heat dissipation layer and the second part; an area of an orthographic projection of the heat conduction assembly on the first part is smaller than an area of an orthographic projection of the heat dissipation layer on the first part; and the driving chip is disposed on a side, distal from the heat conduction assembly, of the second part distal.
