Abstract: A backlight module, including a light-emitting unit, emergent light of which passes through a packaging layer and then is transmitted to a surface of a first reflective layer, then passes through the surface of the first reflective layer and passes through the packaging layer again, enters a light-transmitting substrate from the packaging layer, and is emitted from the side of the light-transmitting substrate distant from the light-emitting unit. The thicknesses of the packaging layer and the light-transmitting substrate are effectively utilized to increase an optical path, thereby reducing the thickness of the backlight module. The first reflective layer is Lambertian. The side of the first reflective layer near the light-transmitting substrate and the side distant from the light-transmitting substrate allow the emergent light transmitted to the surface thereof to be scattered and homogenized to increase the optical path again, and can also function as diffusor plates.
