The present invention discloses a multi-level light guide plate (LGP) and a liquid crystal display (LCD) module. The LGP is divided into multiple sections sequentially connected with each other in a direction, and at least one light bar is disposed at an outward side of each section of said multiple sections. The LCD module has the multi-level LGP, which is located between a liquid crystal panel and a back plate. The multi-level LGP provided by the present invention can achieve local dimming for multiple sections and ensure that light rays of the respective sections will not influence each other.
