ABSTRACT:
A method for forming barrier ribs for a gas discharge display panel which includes the steps of: covering a glass substrate with a conductive ITO film; covering the conductive film with photoresist; exposing the photoresist to radiation; developing the photoresist so as to selectively remove portions of photoresist thereby creating apertures in the photoresist; etching the panel conductive ITO film so as to remove the conductive film in the apertures; depositing barrier rib material including glass particles in the apertures formed in the photoresist until such time as the barrier rib material exceeds the thickness of the photoresist material; and, heating the foregoing combination to a temperature of approximately 580.degree. C. for about 10 minutes to burn off substantially all photoresist material and solidify the barrier material so as to form glass barrier ribs. The glass barrier ribs formed have a shape at least partially defined by the photoresist that was burned off.
