Abstract
The present invention discloses a backlight module and a liquid crystal display (LCD) device using the same. Said backlight module comprises a light emitting diode (LED) light cluster composed of a group of LEDs, and a light guide plate (LGP) which is arranged on the side of said LED light cluster and is coupled with the LED; wherein said backlight module also comprises a limit structure for making the position between said LGP and said LED light cluster be relatively fixed. Because the present invention uses a limit structure for making the position between the edge of said LGP and said LED light cluster be relatively fixed, the limit structure limits the edge position of the LGP; when the tolerance of the LGP is upwards and downwards offset, adjustment can be performed by the limit structure and the edge of the LGP. Meanwhile, the local displacement when the LGP expends with heat can be prevented from occurring. Thus, the coupling efficiency of the LGP and the LED light cluster is increased.
