The invention provides a display device and a backlight module thereof. The backlight module comprises a back plate, a light bar and a radiator. The back plate comprises a bottom plate and a first side plate arranged on one side of the bottom plate. The light bar is arranged on the inner side of the first side plate; the radiator comprises a heat absorption part, a condensation part and a guide pipe communicating the heat absorption part with the condensation part. The heat absorption part is arranged between the first side plate and the light bar and used for absorbing heat emitted by the light bar; the condensation part is arranged on the outer side of the bottom plate. The condensation part and the heat absorption part are arranged on the bottom plate and the first side plate of the back plate respectively, and the condensation part is arranged on the outer side of the bottom plate, so that the heat dissipation capacity of the backlight module can be greatly improved, meanwhile, the design obstacle of a hi
