Abstract

A backlight module and a liquid crystal display device are provided. The backlight module includes a light-emitting assembly, an optical processing assembly and a support structure located between the light-emitting assembly and the optical processing assembly and connected to the light-emitting assembly. The support structure includes a base and a support member, the base being fixedly connected to the light-emitting assembly. The support member has a supporting end and a connecting end. The supporting end faces the optical processing assembly. The connecting end and the base form a backout structure configured to cause the connecting end to back out in a direction away from the optical processing assembly in a case where the supporting end is squeezed by the optical processing assembly, so that can eliminate problems caused by stress concentration of an internal support structure when a backlight module is under pressure.
