Backlight module and display device

The invention relates to a backlight module and a display device, and the backlight module comprises a light guide plate which is provided with a first limiting block, and the first limiting block is provided with a first guide inclined plane; the second frame is arranged above the light guide plate and is provided with a second limiting block, the second limiting block is provided with a second guide inclined surface, the second guide inclined surface is correspondingly matched with the first guide inclined surface so as to guide, assemble and combine with the first guide inclined surface, and when the second frame is pressed and assembled, the second limiting block moves downwards; and the first guide inclined plane and the second guide inclined plane force the first limiting block to move until the first limiting block and the second limiting block are tightly jointed. Therefore, the backlight module can utilize the limiting block inclined surfaces arranged on the light guide plate and the frame to enable
