    • A display device (1) comprises a luminescent display screen (15), and means for directing electrons towards the display screen (15). Said means comprises comprise an arrangement of at least three plates (36, 41, 42), with a middle plate (36) having selection apertures, and selection electrodes associated with the selection apertures. The selection apertures, the selection electrodes and the plates are arranged for having the electron currents, on their way from a source to the electroluminescent screen, selectively pass the apertures in the middle plate and alternately run at opposite sides of the middle plate. An anti-leakage layer (44, eg) for providing in operation a tunneling counteracting potential is provided on a plate of the arrangement to prevent leakage of electrons through gaps between the middle plate and an adjacent plate.
    • 显示装置(1)包括发光显示屏(15),以及用于将电子引向显示屏(15)的装置。 所述装置包括至少三个板(36,41,42)的布置,其中具有选择孔的中间板(36)和与选择孔相关联的选择电极。 选择孔,选择电极和板被布置成具有从源到电致发光屏的途中具有电子电流,选择性地通过中间板中的孔并交替地在中间板的相对侧运行。 用于在操作中提供隧道反作用电位的防漏层(例如,44)设置在该装置的板上,以防止电子通过中间板和相邻板之间的间隙而泄漏。
