ELECTRON EMISSION DEVICE

摘要

An electron emission device is provided to suppress abnormal discharge due to a high voltage of an anode electrode by forming a protective layer on edges of drive electrodes exposed to an internal vacuum space. A first substrate(2) and a second substrate(4) are disposed opposite to each other in order to form an internal vacuum space. An electron emission unit(10) is provided on the first substrate and includes electron emission units and drive electrodes(14,16,18) for controlling electron emission operations and electron beam paths of the electron emission units. An emission unit is provided on the second substrate and includes phosphor layers(24) and anode electrodes(28) formed on one side of each the phosphor layer. A protective layer(36) is formed to cover edges of the drive electrode facing the anode electrodes.
