摘要： A display device capable of realizing a desired color temperature is provided. Phosphor layers (5a,5b,5c) which are excited by ultraviolet radiation produced by discharge and emit red, green and blue visible light, are formed inside a red, green and blue gas discharge tube (1a,1b,1c) respectively. The height (Yc) of the phosphor layer (5c) with respect to a rear support body (20) is higher than the heights (Ya,Yb) of the phosphor layers (5a,5b) with respect to the rear support member (20), and establishes the relationship Yc > Ya = Yb. Therefore, the distance from the phosphor layer (5c) to the opposite discharge surface on a front support body is shorter than those from the phosphor layers (5a,5b), the visible light emitted from the display device (10) is shifted toward blue, that is, the color temperature increases.

摘要： A return path is efficiently and advantageously provided for alternate discharge current flowing between X and Y driver circuits arranged on right and left sides of an AC-driven gas discharge display device of especially a plasma tube array type. The AC-driven gas discharge display device (10) comprises a front-side, transparent substrate (14) and a rear-side substrate (16) sandwiching a plurality of thin discharge tubes arranged side by side. The front-side substrate has, on an inner surface thereof, a plurality of pairs of display electrode (15, Xj, Yj). The rear-side substrate has, on an inner surface thereof, a plurality of address electrodes (Ai) in a direction transverse to the plurality of display electrodes. In the display device, striped light-blocking, electrically conductive films (18) are formed on an outer surface of the front-side substrate at locations corresponding to locations between respective ones of the pairs of display electrode. The light-blocking, electrically conductive films are coupled at their opposite ends to respective points of common reference potential (GNDx, GNDy) in the X- and Y-electrode driver circuits, respectively, to provide a return path for alternate discharge current.
