    • A resin composition for a light diffusion plate is provided to overcome disadvantages of a polystyrene resin, to express excellent light stability, luminance and color coordinate, and to be used in a manufacturing process of a base material layer of a light diffusion plate. A resin composition for a light diffusion plate comprises a polystyrene-based resin; a light diffusing agent; a photostabilizer 0.1-10 parts by weight having the greatest absorption wavelength of 250~320 nm based on the polystyrene-based resin 100.0 parts by weight; and further an HALS-based auxiliary stabilizer 0.1-10 parts by weight based resin 100.0 parts by weight. The photostabilizer is a diamine-based compound, a benzophenone-based compound, a cyanoacrylate-based compound, and a nickel complex compound.
