<p>This invention provides a method of preparing high refractive spherical beads and in particular, there is provided a method of preparing high refractive spherical beads characterized in that they are prepared by preparing an inorganic composite material by adding an inorganic base compound having the refraction index of at least 1.5 to the inside of an inorganic material having porous or hollow air void and reacting them, coating the prepared inorganic composite material with a coating agent and drying the coated inorganic composite material. The high refractive spherical beads in accordance with the invention have excellent dispersion, light properties, UV stability, humidity resistance, thermal dimension stability, and weather resistance and in particular, they have superior heat resistance so that they can effectively prevent bending or yellowing resulting from UV irradiation, heat emission of lamps, heat generated from large-scale LCDs, etc. and they can be usefully applied to large-scale LCDs larger than 40 inches.</p> |
