Beschreibung
Zusammenfassung:	A backlight module comprises a rubber frame, an optical diaphragm, a light guiding plate, a reflecting plate and a light source, wherein the optical diaphragm and the reflecting plate are sequentially accommodated together in the rubber frame; the light guiding plate is arranged between the optical diaphragm and the reflecting plate; a projection is arranged on one side, which is opposite to the reflecting plate, of the light guiding plate, and is used for changing the direction of light; the reflecting plate is provided with a first through hole; the projection is exposed through the first through hole; the light source is arranged on one side, which is far away from the light guiding plate, of the reflecting plate; and the light emitted from the light source illuminates the projection. The backlight module is light and is high in heat dissipation performance. In addition, the invention also provides a liquid crystal display module.
