Abstract
A matrix for a gas discharge display panel, consisting of a plate, made of glass for example, comprising on each of its large faces, an array of parallel grooves; said two groove array are at right-angles to one another and are sufficiently deep for the matrix to be perforated from one side to the other, at the zones of intersection of said groove arrays. Such a matrix, arranged between two slabs, suitably separates the display cells from the electrical point of view, whilst still allowing them to communicate with one another this being an advantage where manufacture and 'conditioning' of the panel are concerned.
