ABSTRACT:
A discharge panel (2) includes substrates (3, 8) bonded together with a gap and ionizable gas sealed within the gap. Discharge electrodes including an anode (9) and a cathode (9a) having a strip pattern are formed on the lower substrate (8) so as to divide the gap into discharge channels (12). A barrier rib (10) is disposed over each anode (9) covering one side wall of the anode (9) so that a portion is exposed to the ionizable gas in the discharge channel (12). The cathodes (9a) are free of the barrier ribs (10) and are exposed to the ionizable gas in the discharge channel (12). The elimination of barrier ribs (10) from the cathodes (9a) increases the effective display region. In an alternate embodiment, the barrier ribs (10), the anodes (9) and a cathodes (9a) are of the same width and same pitch, and provide for a simplification in the manufacturing process.
