Abstract: Disclosed are a display module and a display device capable of minimizing a pressed stain defect while reducing a bezel area. To this end, a thickness of a cushion portion of a cushion plate closer to a bent portion may be reduced, thereby reducing a bending radius of curvature such that the bezel area may be reduced. Further, placing a support layer having a strong supporting force formed of PET into the cushion plate such that the support layer is in contact with the heat-dissipation layer may allow minimizing an unevenness defect on the cushion plate even when a bent pad portion of a display panel presses the cushion portion. Thus, visibility of an internal pressed stain to a user may be minimized.
