The invention relates to a light diffusion plate. The light diffusion plate is integrally composed of a base plate, a plurality of light inlets and spherical structures, wherein the multiple light inlets are evenly arrayed in one side of the base plate in an arrayed mode, and the spherical structures are sunken from the bottoms of the light inlets to the other side; and the other side of the baseplate is a flat face, and light scattering patterns are arranged on the other side of the base plate. From the technical features, it can be seen that after light diffusion plates are mutually spliced, obvious dark lines do not appear on the periphery, and thus shadowless splicing can be achieved; meanwhile, light emitted by a light source is reshaped and subjected to luminous intensity distribution adjustment through the sunken spherical structures, and then the evenly-scattered light appears on the other side of the base plate; according to the light diffusion plate, the light emitted by thelight source can be resha
