PCT No. PCT/JP84/00131 Sec. 371 Date Nov. 21, 1984 Sec. 102(e) Date Nov. 21, 1984 PCT Filed Mar. 23, 1984 PCT Pub. No. WO84/03796 PCT Pub. Date Sep. 27, 1984.The present invention relates to a cathode ray tube suitable for use with a flat type cathode ray tube in which a material from which a secondary electron is emitted by the impingement of an electron beam is exposed on a surface of an area of a first panel portion (2) having on its inner surface formed a phosphor screen on which the electron beam from an electron gun impinges and an insulative material which forms a second panel portion (3) is exposed on an inner surface of the second panel portion (3) opposing the first panel portion (2) wherein the secondary electron is accumulated to present a predetermined high potential state so that an electric field is prevented from being disturbed in a path of the electron beam. |
