    摘要: A DC type gas-discharge display panel comprises a plurality of discharge cells; discharge current limiting means provided for each of the discharge cells, for limiting a discharge current of each of said discharge cells; and a filling gas filled into each of said discharge cells, and having an inert gas mixture. A partial pressure ratio of said inert gas mixture to total pressure of said filling gas is at least 0.95. The above-described inert gas mixture is selected from the group consisting of (1) a first gas mixture consisting of a He gas and a Xe gas, (2) a second gas mixture consisting of a He gas, a Xe gas, and a Kr gas, (3) a third gas mixture consisting of a Ne gas and a Xe gas, and (4) a fourth gas mixture consisting of a Ne gas, a Xe gas and a Kr gas. Assuming now that the total pressure of said filling gas is "p" Torr, a partial pressure ratio of said Xe gas to the total pressure of said filling gas is "x", and also partial pressure ratio of said Kr gas to the total pressure of said filling gas is "k", when said inert gas mixture corresponds to said first gas mixture, a condition of 0.01.ltoreq.x.ltoreq.0.5, a condition of p.ltoreq.600, and another condition of xp.sup.5 .gtoreq.1.4.10.sup.11 are satisfied; when said inert gas mixture corresponds to said second gas mixture, a condition of 0.01.ltoreq.x.ltoreq.0.5, a condition of 0
