ABSTRACT:
A display device with shadowmask CRT comprises an offset scanning means for imparting an offset to the scanning lines. The offset is a shift that gently changes the position of the scanning lines in the Y-axis direction. The offset scanning means imparts the offset in such a way that an interval between neighboring scanning lines is gently changed in accordance with a position in the X-axis direction. The scanning line offset produces some loss in resolution in the Y-axis direction, but since the area which Moire pattern is strongly present coincides with the area of good resolution, even if the offset is imparted in this area, sufficiently high resolution can be obtained.
