Abstract
A light guide composition includes a substrate and a first microstructure layer. The substrate has a first main surface. The first microstructure layer is disposed on the first main surface. A refractive index of the substrate with respect to a first light wavelength is greater than a refractive index of the first microstructure layer with respect to the first light wavelength, a refractive index of the substrate with respect to a second light wavelength is smaller than a refractive index of the first microstructure layer with respect to the second light wavelength, and the first light wavelength is smaller than the second light wavelength.
