Abstract
A light reflecting device includes two substrates and a liquid crystal layer. The two substrates are parallel to each other and respectively electrically connected to a voltage source to generate an electric field therebetween. Each of the two substrates has an inner surface having a horizontal orientation. The liquid crystal layer is formed by liquid crystal materials filled between the two substrates. The liquid crystal materials include liquid crystal molecules and ions of salt species. The liquid crystal molecules are at least formed by negative liquid crystals and chiral molecules. The liquid crystal layer is respectively switched to a diffuse reflection state and a specular reflection state by applying the electrical field generated by the voltage source in a first frequency and a second frequency. The second frequency is higher than the first frequency.
