Abstract: The present invention provides a novel method for the manufacture of an enhanced cold cathode electron emission source allowing a measure of area to be processed at one time. The method includes the steps of: dissolving first and second polymers in solvent to obtain a polymer solution, and applying the polymer solution onto a second conductive layer before forming a hole; precipitating and immobilizing the first polymer in a particulate in the second polymer by evaporating the solvent; removing the first polymer particulate with a developer to form an etching hole in the second polymer; and performing etching process via the etching hole so as to form the hole in the second conductive layer. In one embodiment, the second polymer has greater solubility than the first polymer in the solvent, and the first polymer has greater solubility than the second polymer in the developer.

Abstract: A field emission element including a gate and an emitter and capable of penting any of the element oxide layer from being formed on a tip of the emitter to prevent a decrease in emission current, unstable operation and an increase in noise. The gate has a surface formed of a material of oxygen bonding strength higher than that of a material for at least a tip surface of the emitter, so that oxygen atoms and molecules containing oxygen entering the gate may be captured by adsorption on the gate to prevent formation of any oxide layer on the emitter. When a portion of the emitter other than the tip surface is formed of a material of oxygen bonding strength higher than that of the material for the tip surface, formation of any oxide layer on the tip surface of the emitter is minimized.

Abstract: An image display device capable of minutely setting the interval between an emitter (6) and a gate (5) with high accuracy and of being driven at a significantly reduced drive voltage with good emission uniformity. Each emitter (6) is provided in a recess in a substrate (2), so that the interval between the emitter (6) and a gate (5) is determined depending upon the thickness of the emitter (6). Thus, the interval can be readily controlled by adjusting or varying the period of time during which the film for the emitter (6) is formed, resulting in a micro-interval of the order of sub-microns between the two components being possible with high accuracy.
