Summary:Methods for manufacturing a spacer of a field emission device and a base material used in the spacer are provided to reduce a manufacturing cost by forming a colloid through a screen-printing, a spatula-printing, and a spraying. A colloid is formed on a substrate(11). A patterned photoresist layer(14) is formed on the colloid of the substrate. A pattern of the colloid is formed to have the same pattern of the photoresist layer. The patterned photoresist layer is removed and then the colloid on the substrate is hardened. A release agent(12) is sprayed on the substrate and the colloid is formed on the release agent. The colloid is formed on the substrate through a screen-printing, a spatula-printing, and a spraying. The colloid is glass cement. The release agent is made of a material selected from a group consisting of graphite, ceramic powder, emulsifier, hydrophilic solvent, and a mixture thereof.
