[0025] In the related art, the thickness of the current middle plastic frame is relatively thin, resulting in insufficient wrapping strength, and the rear iron frame is prone to loosening. Therefore, at present, a layer of edge wrapping paper is usually wrapped around the rear iron frame. However, this method is not only cumbersome in operation, but also easy to melt in a high temperature environment, which leads to the loosening of the rear iron frame.

[0026] In view of the above problems, the embodiments of the present application provide a backlight module that is anti-loosening, which can simplify the process of fixing the rear iron frame and can also ensure that it will not loosen even in a high temperature environment.
