Abstract
A flat configuration CRT has a plurality of line cathodes arrayed with a predetermined pitch, a focus electrode section for focusing respective electron beams which are emitted for the line cathodes, and pairs of deflection plates having opposed deflection electrodes for executing deflection of the focussed electron beams, the deflection electrodes of each deflection plate being divided into at least two parts, and an image display section upon which the electron beams are incident. The length of a region in which deflection is executed by the deflection electrodes is made no greaer than a value which is approximately three times the pitch of the line cathodes.
