The present invention relates to a polypropylene composite resin light diffusion plate. The polypropylene composite resin light diffusion plate obtained by mixing hollow spheres made of an inorganic material with an eco-friendly, inexpensive, low specific gravity polypropylene composite resin can improve thermal expansion characteristic (area expansion rate) to a level equal to or superior to those of polycarbonate (PC) and polystyrene (PS), enhance optical characteristics (transmittance, shielding rate), and reduce manufacturing costs. The polypropylene composite resin light diffusion plate according to the present invention is manufactured in a flat plate shape by mixing a plurality of hollow spheres with a polymer resin containing a polypropylene (PP) resin and has an area expansion rate of 0.4-0.7% at 60° C., relative to an area at room temperature, due to mutual bonding of the polypropylene (PP) resin and the plurality of hollow spheres by covalent bonding therebetween.
