ELECTRON SOURCE DEVICE AND DISPLAY |
摘要 |
An electron source device comprising a porous layer (for example, a porous alumina layer), which is composed of an insulator and has many microholes extending in a direction perpendicular to the major surface, and first and second conductor layers disposed on both sides of the porous layer is characterized in that the current density (I/S) is 1 muA/cm2 or higher when a direct current voltage is applied between the second conductor layer and the first conductor layer while using the second conductor layer as an anode. In this case, S represents the overlapping area among 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. A display having a high luminous efficiency and high reliability can be realized by using this electron source device.
