1. A display module, comprising a display panel, a backplane on a side away from a light outgoing surface of the display panel, and a backlight assembly between the display panel and the backplane,
wherein the backlight assembly comprises a light guide assembly, the light guide assembly comprises an optical film layer, a light guide plate and a reflective sheet sequentially arranged along a direction away from the display panel, and the backlight assembly further comprises a lateral backlight source arranged opposite to the light guide plate; the backplane comprises a backplane body on a side of the backlight assembly away from the display panel;
the backplane body comprises a contact structure recessed in a direction from a side away from the light guide assembly toward a side close to the light guide assembly, and the contact structure is in contact with the light guide assembly; a receiving space is between the backplane body and the light guide assembly and on a side of the contact structure close to the lateral backlight source; an elastic contact member is in the receiving space and is in contact with the backplane body and is closely adjacent to the light guide assembly; and
the display module further comprises an intermediate frame; the intermediate frame comprises an intermediate frame body surrounding the backlight assembly; the intermediate frame further comprises a first limit protrusion adjacent to a surface of the light guide assembly close to the display panel; and the first limit protrusion coordinates with the elastic contact member to limit the light guide plate;
wherein the backplane further comprises a first backplane side edge on a side of the lateral backlight source away from the light guide plate; and the first backplane side edge is provided with a bent portion, which extends from the first backplane side edge to a side of the lateral backlight source away from the backplane body.
