Abstract
An object of the present invention is to provide a fluorescent display tube with a touch switch allowing electrodes such as touch electrode, anode electrode, and wirings thereof to be formed on the same substrate at the same time, and having an easy structure, and to provide a method of forming the electrodes and wirings of the fluorescent display tube. The anode electrodes, the touch electrodes, the shield electrode, and the anode wirings are formed on the front substrate. The shield electrode is formed in between the touch electrodes and the anode electrodes, and in between the touch electrodes and the anode wirings. The shield electrode is made of a continuous single conductive film. The touch electrodes are so formed as to surround the corresponding one of the anode electrodes.
