  • Patent number: 7568828
    Abstract: A light guide plate includes a light incidence surface, a light reflection surface, and a light emission surface. The light reflection surface forms a plurality of light-guiding structures extending in a direction substantially parallel to a light source. The light reflection surface has an edge margin section adjacent to the light incidence surface and having opposite end zones each containing auxiliary light-guiding structures that extend in a direction substantially perpendicular to the light source and has an irregular V-shaped cross-section defined by a long inclined side, which faces endwise, and a short inclined side. The auxiliary light-guiding structures are distributed from a densest condition at each end portion toward a sparsest condition at a middle portion of the edge margin section. The long side helps to redirect a greater amount of light to a desired light emission direction thereby enhancing uniformity of light emission of the light guide plate.
