Abstract
A polarized and microstructural light-guide device comprises a non-polarized light source module, a polarized and spectral structure and a polarization conversion module, the non-polarized light source module comprises a light-guide plate and a light source beside the light-guide plate, the material of the light-guide plate is PMMA with the characteristic of high transparency, the surface of the light-guide plate has a plurality of light-emit structures, the polarized and spectral structure is a nanometer structure and comprises a dielectric raster layer and a metal raster layer, and the dielectric raster layer and the metal raster layer are vertically stacked with each other, the dielectric raster layer is integrally formed on a surface opposite to the surface with the plurality of light-emit structures, the polarization conversion module is disposed on the surface with the plurality of light-emit structures of the light-guide plate.
