摘要：
A method drives a spatial light modulation device to record an image into the device. The device includes first and second light modulation layers. The method includes exposing the device to imagewise light while applying a first voltage between electrodes of the first light modulation layer. If the second light modulation layer has such a characteristic that a curve of an intensity of light, which has the same wavelength as the imagewise light and is applied to the second light modulation layer, versus a reflectivity of the second light modulation layer after finishing applying the light has a local maximum point, an intensity of the imagewise light in the exposing is larger than an intensity, which the curve has at the local maximum point, and in the exposing, the second light modulation layer has a reflectivity lower than a reflectivity, which the curve has at the local maximum point.
