ABSTRACT:
A gas discharge-type display panel which comprises a front side glass substrate having a pattern of an anode on one side thereof and a rear side glass substrate having a pattern of a cathode in face-to-face and spaced relation with the anode. The substrates are assembled to seal off so that discharge spaces are created between the substrates. The cathode is made of a conductive composite oxide having a perovskite structure of a K.sub.2 NiF.sub.4 -type structure with significantly improved discharge characteristics and a prolonged life.
