Abstract

PURPOSE:To perform a color display by arranging a comb-like positive column control electrode on an inner surface of a pair of substrates at a point near an anode electrode and generating positive columnes between a plurality of cathode and anode electrodes to excite a fluorescent substance. CONSTITUTION:Near an anode electrode 6 arranged on the inner side of a substrate 2, an elongated comb-like positive column control electrode 25 is disposed in a face- to-face relation to the spacing between adjacent negative electrodes a1, b1, c1, a2, b2, c2..., the inner surface of either one of a pair of substrates 1 and 2 is coated with a fluorescent substance 28, thereby generating positive columns between the electrode a1, b1, c1, a2, b2, c2... and the anode electrode 6 and exciting the fluorescent substance 28.
