A display device which comprise a color cathode ray tube including a finely perforated shadow mask having a multiple of minute apertures defined therein in a predetermined pattern in a vertical direction relates to scanning lines depicted by electron beams, a horizontal deflecting unit for causing the scanning lines to sweep in a horizontal direction, a vertical deflecting unit for displacing the scanning lines of the electron beams in a vertical direction to permit the scanning lines to assume equally spaced relationship with each other, and a scanning line position adjusting unit for displacing every other scanning line from the total number of the scanning lines in the vertical direction in a quantity required to minimize the appearance of Moire pattern.
