PROBLEM TO BE SOLVED: To prevent flickers from occurring without increasing frame frequency when displaying gradations by FRC in a display device selecting a plurality of lines. SOLUTION: The flickers can be prevented from occurring by using a gradation control part 191 for shifting a gradation register outputting gradation data by horizontal and vertical synchronizing signals 193, 194 and a shift value holding RAM 201, appropriately varying the value of the shift value holding RAM 201 by a microcomputer 202, and dispersing on-off patterns at random in the same frame plane and between frames.
