A backlight module includes a back plate having a trench, a light guide plate disposed on the back plate, a reflecting sheet disposed between the back plate and the light guide plate, a heat dissipation module, and a light emitting element. The heat dissipation module includes a heat dissipation element, a heat conducting element, and a position-limiting element. The heat dissipation element is disposed on the back plate. The heat conducting element is disposed in the trench. One end of the heat conducting element is aligned with the heat dissipation element. The first position-limiting element is detachably assembled in the trench and supports the reflecting sheet. One section of the heat conducting element is pressed onto a bottom wall of the trench by the first position-limiting element. The light emitting element is disposed on the heat dissipation element and faces one side of the light guide plate. |
