PROBLEM TO BE SOLVED: To make unevenness of contrast (scroll noise) which moves to a screen slowly in a fixed direction, inconspicuous. SOLUTION: A display data Vd which is supplied so that gradation of a plurality of pixels may be designated in a predetermined order of pixels, is stored in a memory, and thereafter, it is read out with a double speed of the supply speed of the display data, a flyback period is adjusted so that a driving period being the total of a scan period and the flyback period, which is required for the reading, may match an integer multiple of a period of a driving signal Fla of a light source. At this time, correspondence relationship between the display data to be written in the memory and the display data to be read out from the memory is made mismatched (asynchronous) for each predetermined frame.
