摘要： Fluorescent material for display unit (1) comprising fluorescent substance matrix particles (2) constituted substantially of zinc sulfide of crystal structure composed mainly of, for example, hexagonal crystal or cubic crystal. First activator (3) is localized in surface layer part (2a) of the fluorescent substance matrix particles (2). Second activator is uniformly dispersed in the fluorescent substance matrix particles (2). The color of light emitted from a fluorescent substance of zinc sulfide having a crystal structure of, for example, hexagonal crystal can be improved by such a particle structure. Alternatively, unwanted light emission attributed to an electron beam on the low voltage side of the fluorescent substance for display unit (1) can be suppressed.

摘要： An electron source device includes a porous layer (for example, porous alumina layer) which is composed of an insulator and has many microscopic holes provided in a direction perpendicular to a main surface, and first and second conductor layers placed on both sides of the porous layer, and is characterized in that the current density I/S is 1 μA/cm2 or higher when a direct-current voltage is applied between the second conductor layer and the fist conductor layer while using the second conductor layer as an anode. In this case, S represents the overlapping area of the first conductor layer, the second conductor layer and the porous layer. Consequently, an electron source device having a high electron emission ability and a long life even when the degree of vacuum is low can be obtained at low cost, and hence, a display having a high luminous efficiency and high reliability can be realized.
