Abstract:
PURPOSE: A method of manufacturing a cathode electrode in a field emission surface light source reduces process time and costs by selecting and spreading an electrode unit and/or a non-electrode unit when a carbon nanotube ink layer is formed. CONSTITUTION: An electroless plating layer (120) is formed by electroless-plating a substrate. An electrode pattern (130) divided into an electrode unit and a non-electrode unit is formed on the electroless plating layer. A first metal layer (140) is formed on the electrode unit by performing first electroplating. A second metal layer (150) is formed on the first metal layer through second electroplating. A carbon nanotube ink layer (160) is formed on the electrode unit, or the carbon nanotube ink layer is formed on the electrode unit and the non-electrode unit. The non-electrode unit is removed.
