Supporting structure, backlight module and display device

The utility model provides a supporting structure, a backlight module and a display device, and belongs to the technical field of display. The supporting structure is used for supporting an optical film in the backlight module. The supporting structure comprises a base, a first light blocking part, a second light blocking part, an elastic bridge and a supporting piece. Wherein the first light blocking part and the second light blocking part are arranged on one side of the base and are arranged along a first direction; the elastic bridge is arranged between the first light blocking part and the second light blocking part and is used for stretching out and drawing back in the thickness direction of the base; the supporting piece is arranged on the side, away from the base, of the elastic bridge. The orthographic projection of the first light blocking part and the orthographic projection of the second light blocking part on the first plane are overlapped with the orthographic projection of the surface, away from the base, of the elastic bridge on the first plane; the first plane is a plane perpendicular to the first direction. Through the supporting structure provided by the embodiment of the invention, the problem that strong bright spots are formed on the surface of the optical film is solved.
