    • An electron emission device includes a substrate, first electrodes formed on the substrate, electron emission regions electrically connected to the first electrodes, and second electrodes placed over the first electrodes such that the second electrodes are insulated from the first electrodes. The second electrodes have openings to expose the electron emission regions. A third electrode is placed over the second electrodes such that the third electrode is insulated from the second electrodes. The third electrode has openings communicating with the openings of the second electrodes. Each of the electron emission regions and the second electrodes simultaneously satisfy the following conditions: D2/D1≦0.579,   (1) and D2≧1 μ   (2) where D1 indicates the width of each of the openings of the second electrode, and D2 indicates the width of each of the electron emission regions.
    • 电子发射装置包括基板,形成在基板上的第一电极,与第一电极电连接的电子发射区域,以及设置在第一电极上的第二电极,使得第二电极与第一电极绝缘。 第二电极具有露出电子发射区的开口。 第三电极放置在第二电极上,使得第三电极与第二电极绝缘。 第三电极具有与第二电极的开口连通的开口。 每个电子发射区域和第二电极同时满足以下条件:<线内公式描述=“在线公式”end =“lead”→D2 / D1 <= 0.579,(1) in-line-formula description =“In-line Formulas”end =“tail”?> <?in-line-formula description =“In-line Formulas”end =“lead”?>和<?in-line-formula description =“In-line Formulas”end =“tail”?> <?in-line-formula description =“In-line formula”end =“lead”?> D2> = 1 mu(2)<?in-line -formulae description =“In-line Formulas”end =“tail”?>其中D 1表示第二电极的每个开口的宽度,D 2表示每个电子发射区域的宽度。
