Abstract: A backlight module applicable to a key module is provided, the key module includes a plurality of key units and a baseplate, and the plurality of key units are disposed on the baseplate. The backlight module includes a lower substrate, a plurality of periphery light sources disposed along the peripheral of the baseplate, and a shielding structure. The lower substrate is disposed below the baseplate, and there is an outer edge gap between an outer edge of the baseplate and the lower substrate. The periphery light sources are disposed between the baseplate and the lower substrate. The shielding structure is disposed outside those periphery light sources distributed, to prevent light provided by the plurality of light sources from being emitted out of the outer edge gap.
