Abstract
A compensating device for raster distortion is provided, which can compensate a raster distortion, preferably including an inner pincushion distortion, by a simple and inexpensive configuration. The compensating device comprises an electromagnet and a pair of permanent magnets. The electromagnet is disposed outside of a deflection yoke and at a center portion of a side of a beam-deflection area, and generates magnetic poles in the direction along the side. The pair of permanent magnets are disposed beyond the ends of the side, and generate magnetic poles aligned with the magnetic poles of the electromagnet.
