Abstract: There are provided cold cathode fluorescent lamp with high quality and high reliability and method of manufacturing the cold cathode fluorescent lamp, the cold cathode fluorescent lamp making it possible to reduce the amount of a portion on which a sputter phenomenon occurs thereby reducing the discharge start-up time in the cold cathode fluorescent lamp, and to maintain stable discharge for a long period of time thereby improving the dark start-up characteristic as well as high luminance and long life properties. A cold cathode fluorescent lamp has a cesium zirconate film deposited on inner and outer wall surfaces of each of cup electrodes, and a cesium film obtained by activating the cesium zirconate film and deposited on a phosphor film in the vicinity of each of the cup electrodes, thereby changing the electron emission characteristic on the inner wall surface of each of the cup electrodes during lighting to increase a contacting property to the cesium zirconate film, thus generation of the sputtering of the nickel material forming the cup electrodes is reduced.
