Abstract

The present invention relates to a light guide plate. The light guide plate includes a bottom surface and a plurality of patterns distributed thereon. The method of distribution of the patterns includes: obtaining area density distribution of patterns of light guide plate, and defining the maximum area density of the patterns of unit areas and maximum quantity of same patterns; accounting quantity of same patterns of at least an unit area; randomizedly distributing the same patterns described above to the homologous unit area. The distribution of pattern of light guide plate according to the present invention has a function of preventing others to copy it.
