Abstract
A fluorescent display device capable of controlling impinge of electrons emitted from cathodes on phosphor layers and accomplishing satisfactory luminous display while preventing leakage luminance, the fluorescent display device is so constructed that a display section and a control electrode are arranged on substantially the same plane and the control electrode is provided with a plurality of apertures and arranged on the phosphor layer through an insulating layer of substantially the same pattern. Also, a method for manufacturing a fluorescent display device is disclosed which is capable of decreasing a manufacturing cost and improving productive efficiency while providing a fluorescent display device exhibiting such an advantage as described above. The fluorescent display device is manufactured by superposing a transfer material on a fluorescent substrate structure to transfer the former onto the latter, releasing a base film from the transfer material transferred onto the fluorescent substrate structure, and calcining the fluorescent substrate structure.
