Abstract
A gas discharge tube includes: a elongated tube within which an electron-emissive film is formed, and which is filled with a discharge gas and sealed; a plurality of pairs of display electrodes disposed on a display side of the elongated tube; a signal electrode disposed on a rear side of the elongated tube; and an elongated support member inserted into the elongated tube and extending in the length direction of the elongated tube. The support member has a curved shape so that a curved inner surface thereof forms a discharge space, has longitudinally extending opposite edges, and has a phosphor layer formed on the inner surface of the support member. The support member further has an end wall at each of longitudinally opposite ends thereof. The end walls and the curved inner surface form an elongated depression in the support member.
