ELECTRON EMISSION DEVICE AND ELECTRON EMISSION DISPLAY USING THE SAME

摘要

An electron emission device and an electron emission display using the same are provided to prevent an etching effect of a substrate in an etching process by forming a sacrificial layer between the substrate and a resistant layer. An electron emission device includes a cathode electrode(14) and an electron emission unit(100). The cathode electrode is formed on a substrate(10,12). The electron emission unit comes in contact with the cathode electrode in order to be electrically connected. The cathode electrode includes a sacrificial layer(141), a resistant layer(142), and a main electrode(143). The sacrificial layer includes a first opening and is formed on the substrate. The resistant layer includes a second opening and is formed along a cross direction on the sacrificial layer. The main electrode comes in contact with the resistant layer.
