A backlight module ( 1 ) has a light guiding device ( 2 ) and a light source ( 200 ). The light guiding device has a light guide plate ( 20 ), a reflection member ( 26 ), and a reflection plate ( 210 ). The light guide plate has a light incidence surface ( 211 ) and two opposite light emitting surface ( 22, 23 ), defines a space (not labeled) receiving the reflection member therein, and an opening ( 25 ) for accessing the space. The reflection member has two opposite reflection surfaces ( 28, 29 ), and a plurality of micro dots ( 27 ) provided on the reflection surfaces. A reflection film ( 220 ) is attached to the reflection plate. In assembly, the reflection member is disposed such that the reflection surfaces face the light emitting surfaces of the light guide plate, respectively, and the light source is disposed adjacent to the light incidence surface, the reflection plate is attached to the side surface.
