A display device includes an evacuated envelope having a back wall and a plurality of mutually parallel internal support walls. Each of the support walls comprises a separable first and second wall member. Each of the first wall members has a proximal end in contact with the back wall. The support walls are substantially perpendicular to the back wall so that the support walls partition the device into a plurality of channels. A faceplate assembly integral with one surface of the envelope comprises in combination; a viewing faceplate, a mosaic screen, registration blocks disposed on the inner surface of the faceplate beyond the screen, a plurality of second wall members detachably attached to the registration blocks so that each of the second wall members extend between the distal end of a different one of the first wall members and the screen, and a plurality of discrete shadow masks slidably attached to and extending between adjacent ones of the second wall members. Each of the shadow masks extends along substantially the entire length of a different one of the channels.

A first die having a relief pattern is employed to provide predetermined shape and relative positioning for a first plurality of metal strips. A second die is similarly employed for a second plurality of metal strips Without removing the metal strips from the dies, the strips, still in predetermined shape and position, are bonded to opposing surfaces of an insulating substrate. The bonding process includes bringing the dies, and hence, the metal strips, into contact with the opposing surfaces of the insulating substrate. The bonding process may include the application of heat, pressure, and an electrical field across the bonding interfaces, e.g., anodic bonding.
