Abstract: The present invention relates to a micro-composite pattern lens and to a method for manufacturing same. The micro-composite pattern lens of the present invention has a micro-composite pattern with one or more protrusions formed on one side of the lens having a predetermined curvature, and optical polymer nanoparticles arranged in the lens. The micro-composite pattern of the lens may form a wider angle of light emission, thus enabling an LED source, which is a point light source, to be converted into a surface light source having superior luminous intensity uniformity. The lens of the present invention is advantageous in that a single lens may serve as a light guide plate, a prism plate, and a diffusion plate, this eliminating the necessity of stacking optical plates, which might otherwise be required for conventional backlight units.
