ABSTRACT: In a colour television display tube of the post-deflection-focus type the colour selection electrode comprises a first and a second system of lens electrodes which are connected together in an insulating manner. The lens electrodes of the first system are kept at a defined distance from the lens electrodes of the second system by spacing members of electrically insulating material situated between the facing surfaces of the lens electrodes. The spacing members comprise a core of electrically insulating material which determines the dis- tance between the lens electrodes and a jacket of electrically insulating material which directly adheres to the electrode material by heating. The material of the core has a higher melting point than the material of the jacket so that the core during effecting a connection between the jacket and the electrode material maintains its shape.
