Abstract
A very fine pixel pattern can be formed by first screen printing a conductive paste and electron-emitting carbon paste material in sequence before removing a predetermined portion of the screen-printed layers simultaneously such that remaining portions become a fine pixel pattern. This method not only enables fine pixel pattern formation but also provides an electrode/emitter structure that increases electron emission. Furthermore all these improvements can be made with less manufacturing time and cost.
