The display module comprises a rear shell (1) and an intermediate frame (2), and a display screen (3), an ultra-thin protective cover plate (4), and a protective film (5) which are located on one side of the intermediate frame (2) away from the rear shell (1) and are stacked in sequence. The rear shell (1) has a back plate (11) and a first folded edge (12) bent and extending from the edge of the back plate (11) to the side of the display screen (3). The intermediate frame (2) is located in a region enclosed by the back plate (11) and the first folded edge (12). The ultra-thin protective cover plate (4) has a first surface away from the side of the display screen (3), and a side surface located on the edge. The protective film (5) comprises a first part (51) attached to the first surface of the ultra-thin protective cover plate (4), and a second part (52) coating the side surface of the ultra-thin protective cover plate (4) and extending between the intermediate frame (2) and the first folded edge (12) of the rear shell (1).
