Abstract
A light switching module including a first refractive element, a second refractive element and a shifting device. The first refractive element and the second refractive element include substrates with a plurality of micro-lens structures, patterned retardation microstructures disposed on the plurality of micro-lens structures and birefringent layers on the patterned retardation microstructures. Therefore, the birefringent layers have different optical axis regions. The shifting device can adjust the relative position of the first refractive element and the second refractive element to switch penetrating or refracting of incident light and to change the light switching module to transparent state or opaque state.
