A flat fluorescent display panel, having in parallel an anode plate and a cover plate separated by a frame-type spacer whose central open area defines an inner space for a fluorescent material and electrode structure. The three layers are joined and sealed together such that the inner space may be evacuated. The cover is cut or slit, forming an opening that expose the inner space and permits evacuation. The opening is closed and sealed by a portion of the cover or some suitable sealing structure.
