Abstract: Disclosed is an ultra-thin light guidance device, which is realized through integrating a micro prism set into a light guidance module, and achieving filtering the incident lights by means of a micro grating in said micro prism set, thus only part of the effective incident lights pass through said micro prism set, while the rest of incident lights are reflected back to a bottom light guidance layer and a bottom light reflection plate, so that lights are reflected back and enters into said micro prism set again. As such, in less than 10 mm thickness of the ultra-thin light guidance device, a dot or a line light source is converted to form an evenly distributed and highly efficient surface light source by making use of said micro prism set.
