    • An image display device in which each pixel has a thin-film electron source composed of a lower electrode (which is a signal wire), an electron accelerating layer (which is formed by anodizing the surface of said signal wire), and an upper electrode (which covers said electron accelerating layer and releases electrons), in which the anodized film constituting said electron accelerating layer contains hydrated alumina component and anhydrous alumina component such that their ratio in the side close to the upper electrode is greater than that in the side close to the lower electrode. This structure prevents said thin-film electron source from being deteriorated in diode characteristics by said electron accelerating layer, thereby enhancing the reliability of said image display device.

    • An image display device according to the present invention comprises a back panel on which a plurality of pixels each having a thin film electron emitter are arranged two-dimensionally, a front panel disposed opposite the back panel on which phosphor layer is formed, and a sealing frame with which the back panel and the front panel are fixed mutually to seal the plurality of pixels and the phosphor layer in a space enclosed by the back panel, the front panel, and the sealing frame, and is characterized in that double-layered signal lines each electrically connected to a group of the plurality of pixels are formed on the back panel, each of the double-layered signal lines consists of a lower-level electrode made from a silver paste and an upper-level electrode covering at least a part of the lower-level electrode laminated in this order on the back panel. The lower-level electrode is shaped e.g. by coating a groove formed in a surface of the back panel with the silver paste, and a surface of the upper-level electrode is used e.g. for an electrode of the thin film electron emitter, also. According to the configuration, the present invention reduces wiring resistance of the signal lines each electrically connected to the thin film electron emitters as well as improves planarity of each tunneling junction of the thin film electron emitters to suppress dispersion of electron emission property thereof among the pixels.
    • 根据本发明的图像显示装置包括:背面板,每个具有薄​​膜电子发射器的多个像素二维布置;前面板,与设置有荧光体层的后面板相对设置;以及密封 后面板和前面板相互固定的框架,用于将多个像素和荧光体层密封在由后面板,前面板和密封框所包围的空间中,其特征在于双层信号 在后面板上形成有与多个像素的一组电连接的线,每个双层信号线由由银膏制成的下层电极和覆盖至少一部分的上层电极组成, 的下层电极按顺序层压在后面板上。 下层电极的形状如 通过用银膏涂覆形成在后面板的表面中的凹槽,并且使用上层电极的表面。 对于薄膜电子发射体的电极也是如此。 根据该结构,本发明降低了与薄膜电子发射体电连接的信号线的布线电阻,并且提高了薄膜电子发射体的每个隧道结的平坦度,以抑制像素间的电子发射特性的分散 。
