Abstract: A backlight module and a liquid crystal device are disclosed. The backlight module includes a light guiding plate, a plastic frame, a plurality of light emitting diodes (LEDs), and a reflective sheet comprising a first portion, a second portion bending toward the LEDs and a third portion being bent toward the light guiding plate along the light inlets of the LEDs. Wherein a first portion of the reflective sheet being attached to an undersurface of the light guiding plate, a second portion of the reflective sheet comprising a plurality of openings respectively corresponding to the LEDs, and a third portion of the reflective sheet being attached to an area of the top surface of the light guiding plate, and the area is close to the light inlets of the LEDs. In this way, the light utilization rate is enhanced, and the cost is reduced.
