Abstract
An integrated light guide plate having axial directional luminance distribution has a substrate. The substrate has a light incident plane, a light emission plane and a bottom surface opposite to the light emission surface. The light incident plane has a plurality of V-cuts formed thereon to serve as prisms. The included angle of the V-cuts is between 85° and 105°. A plurality of pyramidal recesses is formed on the bottom surface of the substrate. Given the formation of the V-cuts and the pyramidal recesses, the integrated light guide plate of the present invention provides an enhanced axial luminous intensity without requiring additional diffuser sheets and prism sheets. Accordingly, the integrated light guide plate has a good directional axial luminance.
