Abstract:
A light control member includes a plate-like member including a first flat surface and a second surface facing the first surface. The second surface has at least three prism line groups, each group including a plurality of substantially parallel linear prisms. Each one of the linear prisms of one prism line group intersects the linear prisms of other prism line groups at one intersection point, and each linear prism is formed into a convex shape having a substantially curved outer edge when viewed along its longitudinal direction.
