• wherein the display module comprises a display panel, wherein the display panel comprises a display region, a bending region and a binding region in a first direction, and the bending region is bent so that the binding region is located at a backlight side of the display region. wherein in a case that the bending region is in a bending state, a heat dissipation function layer is arranged between the display region and the binding region, and a first rigid support layer is arranged between the heat dissipation function layer and the binding region,
• wherein the display module further comprises a cover plate arranged at a light-exiting side of the display panel;
• a second rigid support layer is arranged at a side of the binding region away from the display region;
• the cover plate comprises a first region not covered by the display panel, the first region comprises a first sub-region corresponding to the binding region and a second sub-region other than the first sub-region, and a first adhesive barrier layer is arranged on the second sub-region and coupled to the middle frame;
• wherein the display device further comprises a second adhesive barrier layer, the second adhesive barrier layer and the first adhesive barrier layer form an annular structure, and the second adhesive barrier layer covers the second rigid support layer, a portion of the binding region not covered by the second rigid support layer, a portion of the first rigid support layer not covered by the binding region, a portion of the heat dissipation function layer not covered by the first rigid support layer, and a portion of the cover plate.
