摘要：
A display control unit is combined with a display device including a display element and electrodes for applying an electric field to the display element. The display control unit includes a control unit for changing and setting a plurality of voltages applied to the electrodes such that one of the plurality of voltages is fixed, and differences between the fixed voltage and other voltages are kept at a predetermined ratio.
