    • A field emission device (10) includes a sealed container (12) with a first light-permeable portion (120) and an opposite second light-permeable portion (122). A first phosphor layer (14) is formed on the first light-permeable portion. A first light-permeable anode (16) is formed on the first light-permeable portion. A second phosphor layer (18) is formed on the second light-permeable portion. A second light-permeable anode (20) is formed on the second light-permeable portion. A shielding barrel (22) is disposed within the container and electrically connected to at least one cathode electrode (25, 26). The shielding barrel has opposite open ends facing toward the first and the second light-permeable portions respectively. The shielding barrel has an inner surface, and a slurry layer (24) containing conductive nano material is formed on the inner surface of the shielding barrel.
    • 场发射装置(10)包括具有第一透光部分(120)和相对的第二透光部分(122)的密封容器(12)。 在第一透光部上形成有第一荧光体层(14)。 第一透光性阳极(16)形成在第一透光部上。 在第二透光部上形成第二荧光体层(18)。 第二透光性阳极(20)形成在第二透光部上。 屏蔽筒(22)设置在容器内并与至少一个阴极电极(25,26)电连接。 屏蔽筒具有朝向第一透光部分和第二透光部分的相对的开口端。 屏蔽筒具有内表面,并且在屏蔽筒的内表面上形成含有导电纳米材料的浆料层(24)。
