Abstract
A driving method of a stacked light modulating device for recording an image therein, which includes selective reflection layers each having a cholesteric liquid crystal, reflecting light with different wavelengths within a visible range, and being different in a lower threshold value of texture change from a planar to a focal conic texture with respect to an externally applied voltage and an upper threshold value of texture change from the focal conic to a homeotropic texture, and a pair of electrodes disposed outside, includes applying between the pair of electrodes voltages including a voltage Vand have a same frequency, to select an area exceeding or not exceeding the upper threshold value in each of the selective reflection layers, and applying voltages including a voltage Vand have a same frequency different from the voltage V, to select an area exceeding or not exceeding the lower threshold value.
