ELECTRON EMISSION DEVICE, AND FLAT DISPLAY APPARATUS HAVING THE SAME

摘要

An electron emission device and a flat display apparatus having the same are provided to prevent permeation of electric field of an anode electrode into electric field between a cathode electrode and a gate electrode by lengthening a cathode electrode and a gate electrode toward an anode electrode. A first substrate(90) includes an anode electrode(80) and a phosphor layer. A second substrate(110) is disposed at a predetermined position apart from the first substrate. A plurality of cathode electrodes(120) are formed on the second substrate. The cathode electrode has the height greater than the width thereof. A plurality of gate electrodes(140) are formed alternately on the second substrate. The gate electrode has the height greater than the width thereof. An electron emission layer(150) is disposed on a lateral surface of the cathode electrode. A spacer(60) is formed between the first and second substrates in order to maintain a gap therebetween.
