    • The present invention concerns a cathode ray display tube in which the layers of a scattered electrons suppressing material are formed on the surface of a metal back layer on a phosphor layer and the inner surface of a funnel part. Each of the scattered electrons suppressing material layers on the surface of the metal back layer and on the inner surface of the funnel part is formed with an amount per unit area within specific ranges. The scattered electrons suppressing material layer is provided to form a laminated layer which is composed of lamina shaped graphite particles with a diameter which is ten times or more as large as a thickness and an average particle size in terms of spherical volume not more than 2 .mu.m. The scattered electrons suppressing material layers reduce unnecessary light emission due to scattered electrons and improve the contrast of a display image. A projection display system providing a display image with high contrast can be constituted by using the cathode display tubes.
    • 本发明涉及一种阴极射线显示管,其中散射电子抑制材料的层形成在荧光体层上的金属背层的表面和漏斗部分的内表面上。 在金属背层的表面和漏斗部的内表面上的每个散射电子抑制材料层形成在特定范围内的每单位面积的量。 设置散射电子抑制材料层以形成层叠层,其由直径为其厚度的十倍或更多的层状石墨颗粒构成,平均粒径以球形体积计不大于2μm m。 散射的电子抑制材料层减少了由于散射电子引起的不必要的发光,并提高了显示图像的对比度。 可以通过使用阴极显示管来构成提供具有高对比度的显示图像的投影显示系统。
