Abstract

PURPOSE:To provide a means of disverse displays, by arranging two display surfaces, that is , an upper surface and an lower surface, and designing and selecting rationally the display pattern of each display surface and phospher used. CONSTITUTION:A lower display base plate 3 includes a wiring layer, an insulating layer, an anode electrode layer and a phospher layer of red luminous phosphor, and an upper display base plate 4 includes a wiring layer, an insulating layer, an anode electrode layer and a phospher layer of bluish green luminous phospher. Spacers 5, the upper display base plate 4 and the lower display base plate 3 are stuck and sealed respectively by frit glass 6, and a vacuum enclosure is thus formed as a whole. On the other hand, grids 7 are fixed on conductive grid supporters 8 respectively, and filaments 10 are similary fixed.
