A light diffusion plate for an LCD(Liquid Crystal Display) backlight is provided to restrict light diffusing particles from being coagulated and to prevent discoloration generated by a lamp of a backlight unit, due to high light transmissivity, light diffusivity, and luminance and high stability against ultraviolet rays. A light diffusion plate for an LCD backlight contains transparent matrix resin and plural light diffusing particles(10) dispersed in the transparent matrix resin. The light diffusing particle comprises inorganic particles(1) and an organic polymer outline layer(2) formed on the surface of the light diffusing particle. The organic polymer outline layer is graft-polymerized on the surface of the inorganic particle. The inorganic particles are at least one selected from a group consisting of silica, potassium carbonate, barium sulfate, titanium oxide, aluminum hydroxide, glass, talc, mica, white carbon, magnesium oxide, and zinc oxide.
