Abstract
An electrode assembly for display apparatus is disclosed. A plurality of electrodes of different rigidities are provided between a cathode and a fluorescent material through coupling spacers. Plural kinds of coupling spacers are prepared in each of which the materials of a substrate metal, an insulating layer and a glass frit are different from each other and the proportional thicknesses of these components are varied to the extent that the intervals between the electrodes of different rigidities are not changed are prepared. An electrode block is completed by arranging the electrodes and the spacers such as to cancel the rotating moment around the neutral axis of the electrode block and joining them by means of calcination. The assembling accuracy of the electrode block is heightened very advantageously for positional accuracy with respect to the fluorescent screen.
