Liquid crystal display module and display device

The invention relates to the technical field of display and discloses a liquid crystal display module and a display device. The liquid crystal display module includes a display screen and a backlightmodule; the display screen comprises an array substrate, a paired box substrate and a liquid crystal layer arranged between the array substrate and the paired box substrate; lateral walls which are perpendicular to the array substrate and connected with one another end to end in sequence are arranged around the surface, away from the liquid crystal layer, of the array substrate in order to form agroove structure, and the backlight module is arranged in the groove structure. In the liquid crystal display module, the backlight module is directly arranged in the groove structure which is formedby the array substrate and the lateral walls on the surface, away from the liquid crystal layer, of the array substrate; by using the lateral walls and the array substrate for supporting and fixing the backlight module, the bac
