    • The present invention relates to an improved technique of an image display apparatus and a method for manufacturing the image display apparatus. The image display apparatus of the present invention is composed of a rear plate and a face plate disposed opposite to each other, the rear plate being equipped with a plurality of electron-emitting devices, each provided with a pair of electrodes and an electroconductive film including an electron-emitting region disposed between the electrodes, the face plate being equipped with a phosphor for displaying an image by being irradiated by electrons from the electron-emitting devices and a film exposed on a surface of the phosphor, the film comprising a metal or a metal compound material. The improved respects are that a film comprising the same metal or the same metal compound material as the metal or the metal compound material constituting the film exposed on the surface of the phosphor, the film formed on each of the electroconductive films of the plurality of electron-emitting devices to have a thickness in a range from 0.2 nm to 4.5 nm. Thereby, it is possible to provide an image display apparatus capable of keeping the homogeneity of brightness over a long period.
    • 本发明涉及图像显示装置的改进技术和图像显示装置的制造方法。 本发明的图像显示装置由相对设置的后板和面板构成,后板配备有多个电子发射器件,每个电子发射器件设置有一对电极和导电膜,该导电膜包括 设置在所述电极之间的电子发射区域,所述面板配备有用于通过被来自所述电子发射器件的电子照射而显示图像的荧光体和暴露在所述荧光体的表面上的膜,所述膜包括金属或 金属复合材料。 改进的方面是包括与构成暴露在荧光体表面上的膜的金属或金属化合物材料相同的金属或相同的金属化合物材料的膜,在多个电子的每个导电膜上形成的膜 - 设备具有在0.2nm至4.5nm范围内的厚度。 由此,能够提供能够长时间保持亮度均匀性的图像显示装置。
