Abstract

Perfections introduced into a color image display tube comprising, in a wrapping medium in which the vacuum has been made to generate a number of electron beams, an image display screen comprising a large number of regions that are luminescent in different colors, and color selection means provided with a large number of openings that associate each electron beam to luminescent regions of a color, whose color selection means comprises a first and a second lens electrode systems, belonging a lens electrode to the first system being connected to a lens electrode belonging to the second system by means of an insulating member, characterized in that said insulating member is constituted by a sheet of an electrically insulating material that is perforated at least in the region of said openings.
