The invention discloses a radiator structure, backlight module and display device for upright use. The backlight module comprises the radiator structure, a light guide plate and a light source module. The radiator structure comprises a backboard and a heat pipe. The heat pipe is coupled with the backboard and comprises a heat absorption part and a radiating part, wherein the heat absorption part is on a side part of the backboard, and the radiating part is bent upwards from the heat absorption part and is extended to the middle part of the backboard. The light guide plate is arranged above the backboard and the heat pipe, and the light source module is arranged on the heat absorption part and is on one side of the light guide plate. The display device comprises the backlight module and a panel which is arranged above the light guide plate. In the radiator structure, backlight module and display device of the invention, gravity is used to design the structure and shape of the heat pipe, so the integral radiating efficiency is greatly improved compared with that of the radiating structure of publicly known technology; and the problems on cost and technology of the publicly known technology is solved.
