Abstract
A method of making a display panel comprising the steps of providing a glass base plate with an array of slots and securing an anode electrode in each slot; forming parallel depressions in one surface of a thin sheet of metal, and then securing it to the top surface of the base plate, with the unetched surface up and the depressions down, and then removing the material of the unetched surface of the metal sheet down to the depressions to form separate strips of metal as cathodes, on the top surface of the base plate; and finally assembling the other electrodes and parts of the panel with the base plate carrying the anode and cathode electrodes.
