Abstract: A light source device includes a first light-emitting element providing illumination beams, a light guide plate (LGP) divided into light-transmissive regions, an optical thin film, and microstructures. The LGP has a first surface, a second surface opposite to the first surface, and a first light-incident surface connecting the first and second surfaces. The first light-emitting element is beside the first light-incident surface. The illumination beams are capable of entering the LGP through the first light-incident surface. The optical thin film is on the second surface of the LGP. The optical thin film has different thicknesses corresponding to at least two of the light-transmissive regions. The microstructures are on the optical thin film. When the illumination beams pass through the light-transmissive regions corresponding to the different thicknesses of the optical thin film and leave the LGP through the first surface, the illumination beams are converted into color beams with different wavelengths.
