A plasma display device includes a front panel (54) having a glass body (38) secured to a surface of a substrate (32). The glass body has a plurality of channels (40) in its exposed surface with upstanding ribs (44) being between the channels. Conductive first electrodes (48) are on the body with each electrode extending along the bottom of a separate channel. The first electrodes are preferably embedded in the glass body. A transparent front panel is located over a back panel (31) and is seated on and secured to the glass body. A plurality of spaced, parallel second electrodes extend between the front panel and the back panel substantially orthogonally to the first electrodes. Phosphors which emit different colors are coated on the channels and the channels are filled with a plasma gas.

Un écran à plasma comporte un panneau frontal (54) pourvu d'un corps en verre (38) fixé à la surface d'un substrat (32). La face exposée de ce corps en verre est pourvue de plusieurs canaux (40) que séparent des nervures dressées (44). Le corps comporte une première série d'électrodes conductrices (48), chacune s'étendant sur le fond d'un canal distinct. Ces premières électrodes sont, de préférence, encastrées dans le corps en verre. Un panneau frontal transparent, qui se situe au-dessus d'un panneau de fond (31), s'appuie contre le corps en verre et lui est fixé. Plusieurs secondes électrodes, séparées et parallèles les unes aux autres, s'étendent entre le panneau frontal et le panneau de fond selon un plan sensiblement perpendiculaire à celui des premières électrodes. Les canaux, qui sont revêtus de luminophores émettant des couleurs différentes, sont remplis d'un gaz plasma.
