Abstract
A backlight module includes a backplane, a light guide plate, a light bar assembly, and fixing adhesive tape. The backplane includes a bottom plate, a counter plate and a side plate connected to form an accommodating space. The light guide plate is in the accommodating space. The light bar assembly is in a U-shaped slot of the backplane and comprises a flexible circuit board and a light-emitting component. The flexible circuit board is on a side of the light guide plate facing away from the bottom plate, and the light-emitting component is at a side surface of the light guide plate. The fixing adhesive tape is between the counter plate and the flexible circuit board. The orthographic projection of the fixing adhesive tape on the bottom plate does not overlap the orthographic projection of the light-emitting component on the bottom plate.
