PROBLEM TO BE SOLVED: To eliminate fluctuation in display due to uneven temperature distribution in a display screen. SOLUTION: This invention relates to a display driving device which drives a display device having a plurality of display pixels including a cholesteric liquid crystal layer, and the display driving device is equipped with a temperature acquisition means to acquire the temperature of the display device, image storage means to store multi-level image data, a table storage means storing a correction table representing the temperature dependence of data voltages to be applied on the cholesteric liquid crystal layer, a binarizing means converting the multilevel image data stored in the image storing means into binary data, correcting a data voltage corresponding to at least one of the binary values based on the temperature acquired by the temperature acquiring means and based on the correction table stored in the table storing means, and an output means to output the data voltage determined by the binarizing means to the display device.
