A color cathode-ray tube (CRT) having an evacuated envelope with an electron gun therein for generating an electron beam is disclosed. The envelope further includes a faceplate panel having a luminescent screen with phosphor lines on an interior surface thereof. A focus mask, having a plurality of spaced-apart first conductive lines, is located adjacent to an effective picture area of the screen. The spacing between the first conductive lines defines a plurality of slots substantially parallel to the phosphor lines on the screen. Each of the first conductive lines has a substantially continuous insulating material layer formed on a screen facing side thereof. A plurality of second conductive lines are oriented substantially perpendicular to the plurality of first conductive lines and are bonded thereto by the insulating material layer. A cap layer is formed over the plurality of second conductive lines and the insulating material. The cap layer is a semiconducting layer that is used to prevent charge accumulation on the insulating material layer. |
