Abstract
A backlight module and a liquid crystal display (LCD) device using the same are provided. The backlight module includes a light-guide plate and a light source module. The light-guide plate has a first side surface and a second side surface, wherein the second side surface is tangent with the first side surface. The light source module is disposed beside the first side surface and the second side surface of the light-guide plate, and a plurality of first light emitting diode (LED) units and a plurality of second LED units are respectively disposed at portions of the light source module that face the first side surface and the second side surface of the light-guide plate. Thereby, the backlight module has the advantages of high image contrast and low power consumption offered by a direct type backlight module and maintains the thickness of a side-edge backlight module.
