It is possible to better correct dynamic false contours in gradation display made by dividing each field into plural subfields. A motion vector detection section detects a motion vector extending between pixels mutually corresponding between two mutually neighboring fields. A pixel position changing section calculates a pixel position vector indicating from where to acquire data for use in rearranging emission data by multiplying a motion vector ending at a pixel to be rearranged by a predetermined function. Furthermore, when a brightness difference between the pixel from which data is to be acquired and the pixel to be rearranged is larger than a threshold value, the pixel position changing section corrects the calculated pixel position vector to change the pixel indicated thereby to one closer to the pixel to be rearranged until the brightness difference is equal to or smaller than the threshold value.
