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.
