Abstract: A film (carbon and/or diamond) for a field emitter device, which may be utilized within a computer display, is produced by a process utilizing etching of a substrate (704) and then depositing the film (705). The etching step creates nucleation sites on the substrate for the film deposition process. With this process patterning of the emitting film is avoided. A field emitter device can be manufactured with such a film. A field emission device results where the cathod has a continuous film that has not been subjected to etching, and thus has superior emission properties. A pixel in the cathode includes the emitting film deposited directly on the substrate with the conductor deposited on one or more sides of the emitter film. In one embodiment the emitter is in a window formed in the conductor layer.

In the formula I and II, R1 and R2 represent C8-C25 alkyl group, x is an integer of 3-8, m+n is an integer of 3-10 and y+z is an integer of 3-10. Content of the formula I and/or the formula II is 10-45wt.% based on total emulsion composition.
