Abstract: Disclosed are a display module and a display device. The display module includes a flexible screen and a support member stacked sequentially. The support member is located on a backlight side of the flexible screen. The support member includes a fixing portion, a first bending portion and a second bending portion arranged in a first direction, and the first bending portion is located between the fixing portion and the second bending portion. The second bending portion includes a central portion and main bending portions located on two opposite sides of the central portion in the first direction, and stiffness of the central portion is higher than stiffness of the main bending portions. Deformation of the central portion during bending is relatively small, thereby relieving a crease of the central portion, and prolonging an overall service life of the display module and the display device.
