BACKLIGHT MODULE

摘要

A backlight module includes a back plate, light sources, protrusive pieces and a reflective sheet. The light sources are disposed on the back plate. The protrusive pieces protrude from the back plate. Each of the protrusive pieces is located between at least two adjacent light sources. The reflective sheet is disposed on the back plate and has through holes. Each of the light sources passes through a corresponding through hole. The reflective sheet further has cutting line groups. Each of the cutting line groups includes two cutting lines intersected at an intersection point. Each of the intersection points is substantially aligned with a corresponding protrusive piece. Portions of the reflective sheet adjacent to the cutting line groups are warped upwards from the back plate, and respectively resist the protrusive pieces.
