Abstract
In a DC gas discharge type image display apparatus including: a front glass substrate; a rear glass substrate facing the front glass substrate, interposing a discharge gas therebetween; a set of anodes including a plurality of line electrodes formed on the rear glass substrate; a set of cathodes including a plurality of line electrodes placed on the front glass substrate so as to perpendicularly cross the set of anodes; and a plurality of discharge cells, each being provided so as to correspond to each of the cross points of the set of anodes and the set of cathodes, the apparatus being driven in a refresh driving method or a memory driving method, the set of cathodes are formed by a spraying method. The cathodes are made from aluminum, nickel, an aluminum alloy or a nickel alloy. The discharge gas is a mixed gas of He and Xe.
