摘要： A method of manufacturing a light guiding plate comprises steps of: forming a protrusion array composed of a plurality of protrusions (300) on a surface of a substrate (100); and forming reflective layers (301) on side facets of the protrusions (300) respectively, in such a way that, the farther away from a side of the substrate (100) the protrusion (300) with the reflective layer is, the greater the reflectivity of the reflective layer (301) is. The light emitted from the light guiding plate made by the method is relatively uniform, and the heating issue is also avoided.
