Abstract: The screen has a cathode composed of microdots (2) for electron bombardment of an anode (5) provided with luminophores (7) of the primary colours on strips (9) of indium-tin oxide deposited on the glass (6). The strips are separated by insulation (20) whose surface (21) has a secondary emission coefficient less than 1 at least within the range of primary electron energies. Each insulating strip of e.g. silicon dioxide has sufficient resistivity to prevent breakdown between two neighbouring luminophores. Its surface may have a coating of low-emission material (e.g. silicon) to a thickness of about 100 Angstrom with a gap of 5-10 mu m at each edge.
