<p>A backlight module (200) comprises a light guide plate (230), at least one light source (240) and a back plate (210). The back panel (210) comprises a bottom plate (211), four side plates (212) and at least one bridging structure (214). The side plates (212) are respectively perpendicular to the bottom plate (211) to form a space for housing the light guide plate (230), and the bottom plate (211) is used for bearing the light guide plate (230). The at least one bridging structure (214) extends inwards to a certain position from the inner surface of the side plate (212), to bear and position the at least one light source (240) and the light guide plate (230). By arranging the bridging structure (214) used for bearing and positioning the light source (240) and the light guide plate (230) on the side plates (212) of the back plate (210), the relative positions of the light source (240) and the light guide plate (230) can be accurately positioned, achieving higher light coupling efficiency.</p> |
