Abstract
An optical sheet with better brightness-enhancing effectiveness includes a substrate and pluralities of microstructures disposed on the substrate. The microstructures are spaced from one another at a distance d. The cross-section of the microstructure is formed in a triangle which has a base length D. Distance d and base length D satisfy the following equation: 0<d/(d+D)≦0.61.
