摘要： A flat-type fluorescent display device permitting luminous display to be observed through only a front glass cover while substantially increasing luminance. A front glass cover is provided on an inner surface thereof with FECs constituted by cathode lines, insulating layers, emitters and gate lines so as to define light-permeable sections between FECs. A substrate is formed opposite to the light-permeable sections with anodes constituted by anode-lines and phosphor layers. Electrons emitted from the FECs impinge on the anodes, leading to luminescence of the phosphor layer, which is then observed through the light-permeable sections of the front glass cover.

摘要： A field emission type electron source capable of permitting a resistance value between a cathode wiring and each of emitter cones to be set at substantially the same level and increasing packaging density of the emitter cones. The electron source includes stripe-like cathode wirings arranged on an insulating substrate. The cathode wirings each are formed with a plurality of windows, so that a plurality of island-like cathode conductors and resistance layers different in resistance value from each other are formed separate from the cathode wiring. Then, a resistance layer, an insulating layer and a gate electrode are formed thereon. The gate electrode and insulating layer are formed with apertures in a manner to be common to both, in which the emitter cones are arranged, resulting in emission of electrons from the emitter cones of each group unit being rendered uniform.

摘要： A vacuum envelope that can improve the vacuum degree in a field emission device is provided. The vacuum envelope includes the cathode side substrate 2 on which field emission elements are formed and the anode substrate 1 spaced by a predetermined distance in the electron emission direction. At least two openings are formed before sealing the vacuum envelope. The remaining gas is ousted from the vacuum envelope by introducing a high temperature gas inside the vacuum envelope for a predetermined period of time. Thereafter, one of the openings is sealed while the envelope is being evacuated to a vacuum state through the remaining openings.

摘要： A field emission cathode that can uniform the number of electrons emitted from each emitter and can prevent a line defect even when a gate electrode is electrically short-circuited with an emitter. The movement of electrons in a channel formed on the channel forming electrode is controlled by applying a positive voltage to the current control electrode, so that the current supplied from the cathode electrode to the emitter can be controlled. If the emitter is short-circuited with the gate electrode, the increased current density destroys the channel, so that the current supply to the emitter can be stopped.

摘要翻译： 场发射阴极可以均匀化从每个发射极发射的电子数，并且即使当栅极与发射极电短路时也可以防止线路缺陷。 通过向电流控制电极施加正电压来控制形成在沟道形成电极上的沟道中的电子的移动，从而可以控制从阴极供给到发射极的电流。 如果发射极与栅电极短路，则增加的电流密度会破坏通道，从而可以停止对发射极的电流供应。
