    摘要： A control electrode portion for passing electrons through a given electron-passing hole selected from a plurality of electron-passing holes provided on an insulating substrate is formed by coating the insulating substrate with a conductive film and dividing the into a plurality of conductive films as control electrodes. This structure obviates the mesh structure of electrons which are necessary in the case of arranging control electrodes on the insulating substrate, thereby realizing high-definition display devices with improved luminance. In addition, planar display devices provided with a surface insulated substrate produced by forming an insulating film on a conductive substrate having electron-passing holes and a plurality of separate control electrodes arranged on the surface insulated substrate, it is possible to prevent the charge-up effect which obstructs the passage of electron beams and, hence, to enhance the luminance at least by (1) providing a voltage applying circuit for applying a predetermined voltage to the conductive substrate, (2) providing a portion at which the conductive substrate is exposed between the adjacent control electrodes.

    摘要： An electrode for a discharge lamp such as high pressure metal vapor lamps and fluorescent lamps is improved by using an electron emission material comprising lanthanum oxide and yttrium oxide. The electron emission material can be a combination of lanthanum oxide and yttrium oxide with barium.strontium.calcium tungstate or an alkaline earth metal oxide including at least barium oxide.When the electrode is used in a high pressure metal vapor discharge lamp, luminous flux maintenance percent in an initial lightening period is highly improved without forming a black deposition at an end of an arc tube.When the electrode is used in a fluorescent lamp, a formation of a black deposition is prevented and a starting voltage is lowered.

    摘要： A flat display apparatus is disclosed which includes a grid interposed between and spaced apart from control electrodes and an electron source. The grid which includes holes has a higher potential applied than the one applied to a cathode so as to enable electrons to pass through the holes. An additional grid may be interposed between and spaced apart from the grid and the control electrodes. Alternatively, a rear electrode is located between adjacent porous cover electrodes to connect them, and a second rear electrode is located near the rear electrode and has a lower potential applied than the one applied to the cover electrodes.
