Zusammenfassung:	PURPOSE: An optical panel containing reflective beads for backlight is provided to perform uniform brightness by distributing reflective beads on an optical panel. CONSTITUTION: An optical panel(41) is formed by a plurality of reflective beads(42), reflective polyhedron, or mixture thereof. The optical panel includes one of glass, resin, or plastic which is diffusion material. Thickness of the optical panel is 1~10mm. Reflectivity of the reflective beads or reflective polyhedron is more than 90%. A size of the reflective beads or the reflective polyhedron is 10~200um. A total volume of the reflective beads or the reflective polyhedron is 10~30% of a total volume of the optical panel.
