A multicolor gaseous discharge display device utilizes electroluminescent techniques as a plasma environment. A layer of electroluminescent phosphor material is used as the dielectric layer overlying the conductor electrodes in an A.C. plasma device. In one embodiment for generating a two color display, only one of the dielectric layers uses an electroluminescent phosphor for a two color display. In a second embodiment, both dielectric layers use different electroluminescent material for a three color display. A layer of n-type semiconductor material is required between the conductor electrodes and the phosphor dielectric to reduce the electroluminescent voltage threshold, while a refractory layer is used to protect the phosphor against ion bombardment during discharge of said device.
