<p>PURPOSE:To make the electron performance such as the electron emission amount and the electron emission efficiency controllable easily, and to obtain an electron emission element with little unevenness of performance between elements, by composing the part of difference in level of the element with a material whose heat conductivity is different from that of an insulating base, and positioning an electron emission member near the part of the difference in level of the element. CONSTITUTION:Between electrodes 33 and 34 on an insulating base 31, an electron emission regulating member 32 is provided projecting upward. The amount of the difference in level formed by the electron emission regulating member 32 is enough to be 0.1 to 1mum. And the width is enough to be 1/2 the interval of the electrodes. As the electron emission regulating member 32, a material whose thermal conductivity is different from that of the base 31. When a blue plate glass is used as the insulating base 31, for example, an insulating material such as alumina, or a metal material such as Au is used for the member 32. Then, by dispersing and spreading an organic metal between the electrodes and then baking it, a minute metallic particle membrane 35 is formed between the electrodes 33 and 34. By applying a current feeding process to the minute particle member 35, an electron emision member 36 is formed linearly along the part of the difference in level of the electron emission regulating member 32.</p> |
