Abstract:
1. A method of manufacturing an anode panel for a cold cathode field emission display which includes a cathode panel in which a plurality of electron emission areas are provided on a support, and an anode panel in which a plurality of phosphor areas and an anode electrode are provided on a substrate, said cathode panel and said anode panel being joined together at their periphery by a joining member, said method comprising: forming said phosphor areas on said substrate; forming an anode electrode which includes an anode electrode central section covering said phosphor areas and an anode electrode peripheral section surrounding said anode electrode central section and extending from said anode electrode central section, an average thickness of said anode electrode peripheral section being less than an average thickness of said anode electrode central section to reduce a compressive stress due to a difference in thermal expansion between the anode electrode peripheral section and the substrate during heating; and joining the anode panel to the cathode panel by the joining member while heating at a temperature of about 400° C., wherein the reduction in compressive stress between the anode electrode peripheral section and the substrate reduces the occurrence of whiskers or hillocks on the anode electrode peripheral portion.
