ABSTRACT:
A plasma display includes a front panel having a glass body secured to a surface of a substrate. The glass body has a plurality of channels in the exposed surface thereof with upstanding ribs being between the channels. Conductive first electrodes 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 over the back panel 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.
The back panel is formed of at least one and preferably a plurality of layers of a green tape of glass particles in a binder. The layers are stacked one on top of each other and the channels are formed in the surface of one of the layers. The stack is placed on a substrate and fired to bond the layers together and to the substrate. Prior to firing the stack, the first electrodes can be formed on one of the layers so that after firing the electrodes are embedded in the resulting glass body. For a body formed from a single layer of the green tape, the channels are formed in the surface of the layer which is opposite to the substrate.
