A process is disclosed for anodically bonding an array of spacer columns to one of the inner major faces on one of the generally planar plates of an evacuated, flat-panel video display. The process includes the steps of: providing a generally planar plate having a plurality of spacer column attachment sites; providing electrical interconnection between all attachment sites; coating each attachment site with a patch of oxidizable material; providing an array of unattached permanent glass spacer columns, each unattached permanent spacer columns being of uniform length and being positioned longitudinally perpendicular to a single plane, with the plane intersecting the midpoint of each unattached spacer column; positioning the array such that an end of one permanent spacer column is in contact with the oxidizable material patch at each attachment site; and anodically bonding the contacting end of each permanent spacer column to the oxidizable material layer. The invention also includes an evacuated flat panel display having spacer structures which are anodically bonded to an internal major face of the display, as well as a face plate assembly manufactured by the aforestated process.

[ What is claimed is:] [1.] A process for fabricating a flat panel display, said process comprising the steps of:providing a laminar silicate glass substrate;covering the substrate with an anti-reflective layer;covering the anti-reflective layer with a light-absorbing layer;patterning the light-absorbing layer to form a generally opaque matrix which will serve as a contrast mask during operation of the display, said matrix exposing portions of the anti-reflective layer where luminescent phosphor material will later be deposited;covering the matrix and the exposed portions of the anti-reflective layer with a transparent conductive layer;depositing an oxidizable material layer over the transparent conductive layer;patterning the oxidizable material layer to form oxidizable material patches for spacer attachment sites, thereby also exposing portions of the underlying transparent conductive layer;providing a plurality of spacers, each spacer having a bondable surface;positioning the bondable surface of each spacer in contact with a spacer attachment site; andanodically bonding the bondable surface of each spacer to the attachment site with which it is in contact.
