Abstract: This invention relates to a fluorescent screen structure wherein a plurality of first electrodes (for example stripelike selected electrodes) having a plurality of fluorescent substances (especially fluorescent substances of different colors for a color screen) severally deposited thereon and second electrodes (for example stripelike reverse bias electrodes not for electrodeposition) not having the fluorescent substances deposited thereon between these first electrodes are provided on a common base (especially a glass substrate for a fluorescent screen panel) and a field emission display (FED) using this and methods for manufacturing these. According to the invention, even in such cases as when pillars for supporting a high vacuum are formed in an FED, a uniform fluorescent screen can be obtained without the pillars constituting an obstruction and a fluorescent substance can be deposited in such a way that it will not subsequently impair the level of a vacuum in a display in which the fluorescent screen is used and also a fluorescent substance can be deposited in a pattern such as a narrow stripe pattern having fine widths and fine pitches highly precisely and without mixed colors and with good manufacturability.

Abstract: A method of forming a fluorescent screen for a field emission display by electrodeposition comprises: forming a transparent solid electrode or transparent stripe or dot electrodes (1) in an effective area and a guard electrode (3, 8) in an ineffective area surrounding the effective area on the inner surface of a screen panel (13), immersing the screen panel (13) in an electrodeposition solution (12G, 12B, 12R, 12M) containing dispersed particles of a fluorescent material and contained in an electrodeposition tank (11), applying a voltage to the transparent solid electrode or the transparent stripe or dot electrodes, and a reverse bias voltage to the guard electrode (3, 8) to deposit particles of the fluorescent material only on the transparent solid electrode or the transparent stripe or dot electrodes to which the voltage is applied. The guard electrode (3, 8) prevents the deposition of particles of the fluorescent material in the ineffective area.

Abstract: A field-emission display has a phosphor panel assembly comprising a transparent electrode (12), a plurality of coated phosphor layers (15) disposed on said transparent electrode (12) for emitting light in response to bombardment of electron beams emitted from field-emission cathodes, a plurality of black insulating layers (13) disposed between said coated phosphor layers (15), and a plurality of conductive layers (14) disposed on said black insulating layers (13), respectively, between said coated phosphor layers (15) and electrically insulated from said transparent electrode (12) by said black insulating layer (13). The black insulating layers (13) provide a black mask between the phosphor layers to improve the contrast ratio, and the conductive layers are effective to increase the percentage of electron beam utilization, thus improving the quality and resolution of displayed images. These advantages can be achieved without making image display unstable due to charging-up of the black mask and straying of secondary electrons.
