A display control apparatus of a display device which uses a ferroelectric liquid crystal as an operational medium to display or update image data comprises a data storage unit to store data which is displayed on a display device, a supplying unit to supply data to the data storage unit, a detector to detect a difference between the data supplied to the supplying unit and the data displayed at present on the display device, a memory to store data indicative of the result of the detection by the detector, a controller to supply the data stored in the data storage unit to the display device on the basis of the result of the detection stored in the memory, and a counter to count the number of different bits of the line detected by the detector. The detector detects such a difference for every line of the display device. The controller preferentially supplies the data to the display device in descending order of the number of bits counted for each line.
