PURPOSE: An illumination member for USG(Unified Glare Rating) reduction is provided to improve optical efficiency by forming a collimation layer and a diffusion layer. CONSTITUTION: An air plate(200) includes an air region(220). The air region includes an air layer inside. A micro lens layer includes a lens pattern. The lens pattern is integrally formed with an upper plate of the air plate. A diffusion layer is formed in a lower plane of the air plate. |
