Abstract
An image display device is disclosed in which poor display resulting from deflection of electron bundles which occurs due to electrification of spacers and secondary electron emission can be positively prevented and a high-quality display can be therefore obtained. In the image display device, electron sources in the vicinity of the spacers are displaced with respect to arranging positions at equal pitches, by distances which allow drifts of the electron bundles from phosphors, which are brought about by the deflection of the electron bundles which occurs due to electrification of the spacers and secondary electron emission, to be cancelled.
