What is claimed is:

1. A display panel comprising
a gas-filled envelope made up of a base plate having a top surface and a bottom surface and a
face plate hermetically sealed to said base plate,
a plurality of anode electrodes disposed parallel to each other in slots in the top surface of
said base plate and extending along the top surface of said base plate,
portions of said anode electrodes being recessed in
the ends of said base plate, and the ends
of said anode electrodes being secured in
place at the bottom surface of said base
plate, and
cathode electrodes disposed on said top surface of
said base plate and oriented at an angle
to said anode electrodes, said anodes and
cathodes defining rows and columns of gas- filled cells,
said cathodes having their ends terminating adjacent to the bottom surface of said base plate
and secured in place thereat.

2. The panel defined in Claim 1 wherein
said face plate has in its inner surface, parallel,
shallow elongated depressions which lie
transverse to said cathodes in alignment
with selected ones of said anodes, and
an opaque coating on the inner surface of said face
plate and having elongated openings aligned
with said elongated depressions whereby cathode glow at certain portions of said cathodes axe
visible through said openings to a viewer
looking at said face plate.

3. The panel defined in Claim 1 wherein said anodes include scan anodes and display anodes.

4. The panel defined in Claim 1 wherein said anodes include scan anodes and display anodes, and the scan anodes and display anodes alternate with
each other.

5. The display panel defined in Claim 1 wherein each crossing of a cathode and said anodes defines a column of gas cells including scan cells and display cells, the scan cells and display cells alternating with each other.

6. The panel defined in Claim 1 wherein said cathodes comprise flat strips or ribbons.

7. The panel defined in Claim 1 and including terminal pins secured to the bottom surface of said base plate, each anode and each cathode secured to one of said pins .

8. The panel defined in Claim 1 wherein slots are- provided at the ends of said base plate for receiving said anodes and recessing them.
