Abstract
A gas-filled display panel comprising a glass base plate and a glass face plate hermetically sealed together along a perimeter seal area to form an envelope which is filled with an ionizable gas, the base plate having an array of longitudinal slots in which anode wires are seated and having an array of cathode electrodes on the top surface thereof. The base plate has cross grooves transverse to the slots and positioned one near each end of the base plate, and a glass rod is secured in each cross groove with the ends of each rod lying within the seal area between the base plate and the face plate, the top surface of each insulating member being generally coplanar with the top surface of the base plate in the seal area, to insure the formation of a hermetic seal between the base plate and face plate at the cross grooves.
