摘要

A back panel frame (20), comprising: a bracket (201) and a bent part (202). The bracket (201) comprises a bottom plate (2011), a side wall (2012) and a retaining wall (2013), wherein the bottom plate (2011) is connected to the side wall (2012), the bottom plate (2011) is used for supporting an optical component (21) of a backlight module (200), the retaining wall (2013) is arranged at the end of the side wall (2012) away from the bottom plate (2011) for supporting a liquid crystal panel (300), and the bottom plate (2011) and the side wall (2012) mate with the retaining wall (2013) to form a housing groove for housing the side edge of the optical component (21); and the bent part (202) is connected to the retaining wall (2013) for mating with the retaining wall (2013) so as to fix the liquid crystal panel (300). Also provided are a liquid crystal display device and a backlight module (200) thereof. The liquid crystal display device, and the backlight module (200) and the back panel frame (20) thereof can omit the rubber frame, and reduce the costs for moulds and materials, thereby reducing the production costs.
