ABSTRACT:
A field emission cold-cathode device has a supporting substrate, and an emitter for emitting electrons disposed on the supporting substrate. The supporting substrate is essentially formed of a transparent synthetic resin. The emitter is formed by molding a portion of a conductive material layer such as Au which has been disposed on the supporting substrate into a conical shape. The conductive material layer functions also as a cathode wiring. An engaging concave portion is formed on a surface of the emitter to be bonded with the supporting substrate. In conformity with this engaging concave portion, a convex portion is integrally formed on the supporting substrate so as to be hermetically fitted in the engaging concave portion.
