A backlight module includes a film, a light guide plate disposed under the film, and a circuit board disposed under the light guide plate and provided with a light-emitting unit. The film includes a single-key transparent area, a light-shielding area disposed around the single-key transparent area, and a side transparent area disposed adjacent to or along an edge of the film. The light guide plate has a first microstructure group and a through hole correspondingly disposed under the single-key transparent area, a second microstructure group correspondingly disposed under the side transparent area, and a light-transmitting area partially correspondingly disposed under the light-shielding area. The light-emitting unit is accommodated in the through hole. A number of microstructures or a light-emitting area of the second microstructure group is greater than a number of microstructures or a light emitting area of the first microstructure group.
