    • A precursor to an electron source, having a capability for extending the life of an image display device by substantially preventing 1) a degradation in a degree of vacuum provided in an image display apparatus, 2) short-circuiting between adjacent wire electrodes via a getter, and 3) a degradation in performance characteristics of the electron source, even when used for a long time period. The electron source is for coupling to an image display member to form an image display apparatus, and the image display member is for displaying an image in response to being irradiated by electrons. The precursor preferably comprises a substrate, and an antistatic film provided on a surface of the substrate at a region where electron emitting devices are to be disposed on the precursor to form the electron source, but not on a region of that surface to be coupled to the image display member.
    • 具有通过基本上防止图像显示装置中提供的真空度降低的图像显示装置的寿命延长的能力的电子源的前体,2)通过吸气剂在相邻的线电极之间短路 ,3)电子源的性能特性的降低,即使长时间使用也是如此。 电子源用于耦合到图像显示部件以形成图像显示装置,并且图像显示部件用于响应于被电子照射而显示图像。 前体优选包括基底和设置在基底表面上的电子发射器件将被放置在前体上以形成电子源的区域上的抗静电膜,但不在该表面的要耦合到 图像显示构件。
