The present disclosure relates to a backlight module, including a backlight frame and a light guide plate placed inside the backlight frame, wherein a light-emitting element is provided at the inner side of a side wall of the backlight frame, a first reflective sheet is provided at a lower location under the light guide plate along the vertical direction, and a second reflective sheet is provided at a lower location under the light-emitting element along the vertical direction, the second reflective sheet being extended towards the inside of the backlight frame to a lower location under the light guide plate along the vertical direction. Through providing the second reflective sheet located under the light-emitting element and extending to a lower location under the light guide plate, the light scattered out under the light-emitting element can be guided into the light guide plate, thus effectively enhancing the efficiency of incident light guided into the light guide plate from the light-emitting element.
