A plasma addressed electro-optical display is disclosed which is capable of improving current resistance of discharge electrodes disposed below cover glass to be similar to that of discharge electrodes in an effective frame and which, therefore, is enabled to be free from disconnection the reliability to be improved. The plasma addressed electro-optical display has a plasma cell formed by disposing a thin dielectric plate on a first substrate having a main surface on which a plurality of substantially parallel discharge electrodes are formed in such a manner that a predetermined distance is provided between the first substrate and the thin dielectric plate and by hermetically sealing the periphery of the first substrate and the thin dielectric plate with a sealing portion; and a second substrate disposed on the thin dielectric plate and having electrodes intersecting the discharge electrodes at substantially right angles on an opposite surface thereof in such a manner that an electro-optical material layer is interposed between the thin dielectric plate and the second substrate, wherein barrier ribs for separating the plasma cell are formed on the discharge electrodes apart from the sealing portion, a cover glass layer covering the discharge electrodes is formed in at least a region between the barrier ribs and the sealing portion, and assuming that the thickness of each of the discharge electrodes is t, the width of the same in an effective frame is W.sub.1 and the width of the same below the cover glass is W.sub.2, a predetermined equation is satisfied.

Plasma addressed electro-optical display

A method of producing a cathode ray tube comprising forming a phosphor layer on the inner surface of a panel of a glass bulb, forming an lacquer intermediate film on the phosphor layer, removing the lacquer intermediate film formed on the inner surface of the funnel of the glass bulb by a liquid in a state with the temperature of the glass bulb higher than the temperature of the liquid.
