Abstract

This invention discloses an edge-lit LED backlight module, a liquid crystal display device and a method for fixing a reflection sheet. This backlight module comprises a backplate, a sidewall connected to the backplate, a light guide plate arranged on the backplate, a light-emitting device arranged on the backplate, and a reflection sheet arranged between the backplate and the light guide plate; wherein the light guide plate has a light-exiting top surface and a light-entering side adjacent to the light-exiting top surface, and the light-emitting device is located between the light-entering side and the sidewall. This backlight module further includes at least a first tension member and a second tension member with their both ends respectively connected to the reflection sheet and the backplate. The backlight module herein can effectively prevent the reflection sheet from warping caused by thermal expansion and further improve the optical quality of the backlight module.
