Abstract:
1. A driving apparatus for a liquid crystal device, the driving apparatus for recording an image onto the liquid crystal device, the liquid crystal device including at least a liquid crystal layer containing a cholesteric liquid crystal, a photoconductor layer, wherein the liquid crystal layer and the photoconductor layer are laminated, and electrodes disposed outside the liquid crystal layer and the photoconductor layer, the driving apparatus at least comprising: a power source device configured to apply a voltage between the electrodes; an exposure device configured to expose the liquid crystal device while scanning the liquid crystal device; and a controller configured to control the power source device and the exposure device by performing, in order, in the write action, the controller controls at least the power source device and the exposure device so that an electric field energy applied to an exposure portion of the liquid crystal layer gradually increases from a start of a series of scanning actions to an end of the series of scanning actions.
