Abstract
A backlight module, including a light guide plate and a flexible circuit board, wherein an edge of the light guide plate is provided with plural light source mounting holes disposed along a thickness direction of the light guide plate; a light source is mounted in every light source mounting hole in such a manner that a light emitting surface of the light source is attached onto a hole wall of the light source mounting hole; plural groups of anode-cathode conductive parts are disposed on the flexible circuit board in one-to-one correspondence with the plural light source mounting holes, each being connected to an anode and a cathode of the light source in a corresponding light source mounting hole. The backlight module improves the brightness and uniformity of the light entering the light guide plate. A liquid display device including the above-mentioned backlight module is further provided.
