Abstract: A production method of a light guide and a stamper, combining anisotropic etching and isotropic etching. First a plurality of microstructures is formed on a back surface and a front surface of the substrate. By electroforming, rear and front stampers are made from the back and front surfaces of the substrate. Light guides are produced using the rear and front stampers.
