The present invention provides a backlight module and a liquid crystal display apparatus. A light guide plate of the backlight module comprises hollow structures. The hollow structures correspond to the light sources and comprise two air layers with an included angle there-between, and the two air layers are a first hollow layer and a second hollow layer. A normal direction is vertical to the light-incident surface, and there is a first oblique angle between the first hollow layer and the normal direction, and there is a second oblique angle between the second hollow layer and the normal direction. The present invention can prevent the problem of uneven brightness distribution.
