The present invention, a transparent substrate, and relates to an optical device comprising a first transparent layer on the substrate lattice, and the lattice structure is periodically comprises alternating areas having different refractive index. According to the invention, the device comprises a first by a second transparent lattice structure of periodically also includes alternating areas having different refractive index as the location on the grid floor, have more of a first grid layer having a high refractive index zone more to be at least partially aligned with the zones of the second grid layer having a low refractive index, and, to be partially arranged as in the opposite case, the second lattice structure is a non reduces the amount of light that is diffracted into a zero transmission order. The invention for example allows a so-called shown to reduce the rainbow effect in the HUD (head-up displays).
