PROBLEM TO BE SOLVED: To use a small-scale circuit to suppress flicker when generating gradation data which represents a plurality of gradations by changing a blinking frequency with a plurality of frames as one cycle in a FRC (frame rate control) system. SOLUTION: A gradation data generation circuit includes a frame counter 1 for counting with a display frame period, an X coordinate counter 2 for counting with a display horizontal coordinate period, a Y coordinate counter 3 for counting with a display vertical coordinate period, a frame counter conversion means 4 for converting a frame count value outputted from the frame counter 1 to frame count values different among pixels by a X coordinate count value outputted from the X coordinate counter 2 and a Y coordinate count value outputted from the Y coordinate counter 3, and a display data generation means 5 for outputting the frame count value converted by the frame counter conversion means 4 and multi-value input image data as one-bit display data by bit operation.
