Abstract
A video image display apparatus comprising line cathodes for emitting electron beams, a phosphor screen having a phosphor layer which emits light at impingement by said electron beams, and a vacuum enclosure containing the above-mentioned components therein, wherein undesirable vibration is prevented by providing damping strings across and lightly touching the line cathodes for reducing the vibration of the line cathodes by their damping effect.
