Abstract
In a backlight module, a shading film connected to the substrate has a first surface, a second surface and a first hole disposed thereon. The light guide plate is connected to the shading film while a second hole with a greater aperture than that of the first hole is disposed thereon. The shading film has an extra extending section compared to the light guide plate and a shading portion is disposed thereon. A third hole with a greater aperture than that of the second hole is disposed on the reflective sheet. A side of the reflective sheet near the third hole has an extra adhesive section while a side of the light guide plate near the second hole does not. The adhesive section connected to the extending section covers a side of the light guide plate near the second hole for preventing light from exiting through the second hole.
