Abstract

PURPOSE:To make a cathode-ray tube thin by decreasing the space occupied by a deflection means by making, in this invention especially, the thickness of a deflection york constituting a second deflection system small by carrying out both horizontal and vertical deflections by means of the same second deflection system. CONSTITUTION:The second deflection system, which horizontally and vetically deflects electron beams discharged from an electron gun 4, is constituted between the locations of an electron gun 4 and a fluorescent screen 2. A horizontal-vertical-deflection means 6 carries out, for example, a horizontal deflection of a relatively large deflection angle through an electromagnetic deflection, and carries out the vertical deflection through an electrostatic deflection by using, for example, a pair of inner ball pieces used as an electromagnetic horizontal deflection also as an electrostatic deflecting plate. In this invention, the total thickness of a deflection york 20 can be decreased by making the thickness (D1) of the york 20 equal to the thickness (d1) of the plate-like core.
