1. A backlight module comprising:
- a light guide plate having a light incidence surface and a light-emitting surface opposite to the light incidence surface;
a reflecting member spaced apart from the light guide plate and facing the light incidence surface; and
a plurality of light sources arranged between the reflecting member and the light guide plate;
wherein the light guide plate defines a plurality of hollow structures therein, each of the hollow structures corresponds to one of the light sources, a plurality of microstructure units are defined on the light incidence surface, and each of the microstructure units is over the corresponding light source.

Abstract
A backlight module (20) includes a light guide plate (23), a reflecting member (21) and a plurality of light source (22). The light guide plate has a light incidence surface (231) and a light-emitting surface (232) opposite to the light incidence surface. The reflecting member faces the light incidence surface of the light guide plate. The light sources are arranged between the reflecting member and the light guide plate. The light guide plate defines a plurality of hollow structures (25) therein corresponding to the light sources and has a plurality of microstructure units (27) defined on the light incidence surface corresponding to the light sources.

19. A display device comprising:
-
a light source installable beside a display side of said display device to provide light to said display side for display; and a light guide member of said display device extending along said display side of said display device and located between said display side and said light source to accept said light from said light source and further transmit said light toward said display side, said light guide member comprising a hollow structure formed inside said light guide member and around a projective area of said light source upon said light guide member to create void inside said light guide member for enhancing uniformity of said transmitted light in said light guide member, said hollow structure arranged discontinuously inside said light guide member and distributed symmetrically to said projective area. - View Dependent Claims (20)
