    • An electron emission display includes first and second substrates facing each other, a plurality of driving electrodes formed on the first substrate, a plurality of electron emission regions controlled by the driving electrodes, a focusing electrode disposed on and insulated from the driving electrodes and provided with openings through which electron beams pass, a plurality of phosphor layers formed on a surface of the second substrate, an anode electrode formed on surfaces of the phosphor layers, and a plurality of spacers for maintaining a gap between the first and second substrates. Among the electron emission regions disposed in the opening adjacent to the spacer, one electron emission region, which is closest to the adjacent spacer, is spaced apart from an inner wall of the opening by a first distance that is different from a second distance from another electron emission region, which is farthest from the adjacent spacer, to the inner wall of the opening.
    • 电子发射显示器包括彼此面对的第一和第二基板,形成在第一基板上的多个驱动电极,由驱动电极控制的多个电子发射区域,设置在驱动电极上并与驱动电极绝缘的聚焦电极, 电子束通过的开口,形成在第二基板的表面上的多个荧光体层,形成在荧光体层的表面上的阳极电极以及用于保持第一和第二基板之间的间隙的多个间隔物。 在与间隔物相邻的开口中设置的电子发射区域中,最靠近相邻间隔物的一个电子发射区域与开口的内壁间隔开距离与第二距离不同的第一距离 电子发射区域,其距离相邻的间隔物最远,到开口的内壁。
