Abstract

PURPOSE:To obtain a cathode-ray tube suitable for a large image display apparatus having an immense picture surface by forming the cathode into a band shape and forming the control electrode and accelerating electrode into mesh forms. CONSTITUTION:The fluorescent surface 10 constituted of a fluorescent layer 8 and metal backing 9 is formed on the bottom surface 7 of a lower case body 3. An accelerating electrode 11 is arranged, extending in parallel to the fluorescent surface 10, on an upper case body 2, and a control electrode 12 is arranged in parallel to the accelerating electrode 11, keeping a prescribed distance. The accelerating electrode 11 and control electrode 12 are each formed of mesh-shaped flat electrodes. Substantially at the center on the back of the control electrode 12, a cathode 14 is arranged, keeping a prescribed distance from the control electrode.
