Abstract: A backlight module includes a masking plate, a light guiding plate, a light emitting unit, a reflective plate and an attaching layer. A plurality of upper through holes are formed on the masking plate. An upper attached area is defined by a periphery of each of the upper through holes. The light guiding plate is disposed below the masking plate with a plurality of penetrating holes formed thereon. The light emitting unit is located on a lateral side of the light guiding plate and. The reflective plate is disposed below the light guiding plate. A plurality of lower through holes are formed on the reflective plate and located corresponding to the penetrating holes. A lower attached area is defined by a periphery of each of the penetrating holes. The lower attached area is attached to the upper attached area by the attaching layer via the penetrating hole.

Abstract: A backlight module includes a light guide plate, a light source, a light shielding sheet, a light reflecting sheet and a light shielding member. The light guide plate has a hole formed thereon and the hole has a side wall. The light source is disposed neighboring to the light guide plate and used for emitting light into the light guide plate. The light shielding sheet is disposed on the light guide plate. The light reflecting sheet is disposed below the light guide plate. The light shielding member is disposed in the hole and covers the side wall of the hole, so as to block the light guided by the light guide plate from being emitted out of the hole.
