Abstract: A backlight module and an electronic device are provided. The electronic device includes a display panel and a backlight module. The backlight module includes an outer frame and an inner frame. The inner frame is disposed inside the outer frame. The outer frame is provided with a positioning portion. A fastening portion is formed on an outer wall of the inner frame. A cross-section of the positioning portion does not directly contact the fastening portion, which can avoid the wear of the fastening portion caused by the cross-section of the positioning portion and reduce a debris generated by the friction between the outer frame and the inner frame at a snap-fit engagement position of the fastening portion and the positioning portion.
