Abstract
A light sheet including: a substrate layer including a transparent matrix; and an anisotropic light diffusing layer including an array of elliptical lenses arranged on a first surface of the substrate layer. The anisotropic light diffusing layer anisotropically scatters light that is input therein, before transmitted it to the substrate.
