<P>PROBLEM TO BE SOLVED: To provide an image data modulation device that reduces EMI, and to provide an image display apparatus. Ž<P>SOLUTION: The image data modulation device includes a difference modulation part for input of digital image data and for output of a difference with respect to stored data as VDdata, a surplus reduction part for converting the VDdata into surplus reduced data compressed by 1 bit based on surplus function to output it, and a differential signal modulation part for converting the surplus reduced data into a serial signal to output it. The surplus reduction part converts one having a large appearance probability of the VDdata corresponding to one having a small transition amount of the surplus reduced data. The serial signal contains the surplus reduced data of one pixel arrayed in order from an upper bit side to a lower bit side or in order from the lower bit side to the upper bit side.
