Display module and display device

The invention discloses a display module and a display device, and belongs to the technical field of display. The display module comprises a protective cover plate, a flexible display panel and a metal heat dissipation layer. A protective cover plate in the display module is arranged on the light emitting side of the flexible display panel. The orthographic projection of the edge part of the flexible display panel on the protective cover plate can be located in the bent part of the protective cover plate. Therefore, the edge part of the flexible display panel can extend into the bent part in the protective cover plate. Therefore, after the flexible display panel is attached to the protective cover plate, the overall frame of the obtained display module is narrow, the screen-to-body ratio of the display module is large, and the use experience of a user is improved. After the display module is integrated into the display device, the overall frame of the display device is small, and the modification effect on the display device is improved.
