    Abstract: A light source has a transparent substrate, a fixed substrate disposed in facing relation to the transparent substrate, at least one electron emitter disposed on the fixed substrate, a phosphor layer disposed on a surface of the transparent substrate which confronts the fixed substrate, and a trajectory deflector for deflecting the trajectory of a pulsed electron flow intermittently emitted from the electron emitter. The pulsed electron flow is deflected by the trajectory deflector to two-dimensionally scan a position of the phosphor layer which is irradiated with the pulsed electron flow for thereby spreading the pulsed electron flow.

    Abstract: 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.
