Abstract: Electrophoretic deposition provides an inexpensive, efficient process for manufacturing a field emission cathode. Particles of a resistive material are deposited by electrophoretic deposition on a conducting layer overlying an insulating layer. An electron emitting layer is then applied over the resistive material to produce the cathode. By controlling the composition of the deposition bath, an electrophoretic deposition process can be used to efficiently produce field emission cathodes that provide a spatially and temporally stable emission field. The deposition bath for the field emission cathode includes an alcohol, a charging salt, water, and a dispersant. The field emission cathodes can be used as an electron source in a field emission display device.
