Title: BACKLIGHT MODULE AND LIQUID CRYSTAL DISPLAY DEVICE USING SAME
Abstract:
A backlight module (1) and a liquid crystal display device using same. The backlight module (1) comprises a middle frame (12), a light guide plate (11) and a light source (3), and is characterized by further comprising a shielding structure. The shielding structure prevents the light of the light source (3) being directly emitted out from a gap between the middle frame (12) and the light guide plate (11) and comprises a groove (121) arranged on the middle frame (12) and a convex lug (111) disposed on the light guide plate (11). The convex lug (111) is arranged in the groove (121). Due to the shielding structure, the light cannot be directly emitted to an optical film (13) from the gap between the middle frame (12) and the light guide plate (11), the problem of light leakage is resolved, bright lines and light spots cannot appear on a liquid crystal display panel (2), and accordingly the quality of the liquid crystal device is improved.
