Abstract
A display device capable of realizing a desired color temperature is provided. Phosphor layersandwhich 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 tubeandrespectively. The height Yc of the phosphor layerwith respect to a rear support bodyis higher than the heights Ya and Yb of the phosphor layersandwith respect to the rear support memberand establishes the relationship Yc>Ya=Yb. Therefore, the distance from the phosphor layerto the opposite discharge surface on a front support body is shorter than those from the phosphor layersandthe visible light emitted from the display deviceis shifted toward blue, that is, the color temperature increases.
