Abstract
A method of manufacturing a field emission device having emitter shapes, comprise the steps of forming a first original plate having a major surface provided with emitter shapes, by cutting a surface portion of a base material, forming a first material layer on the major surface of the first original plate on which the emitter shapes are provided; separating the first material layer from the first original plate, thereby obtaining a second original plate having recesses onto which the emitter shapes on the first original plate are transferred, forming a second material layer on a major surface of the second original plate on which the recesses are provided; and separating the second material layer from the second original plate, thereby to obtain a substrate having projections portions onto which shapes of the recesses of the second original plate are transferred.
