Electric field emitting source, element using same, and production method therefor

摘要

An electric field emitting source is equipped with an electron emitting film which comprises a nano-sized electron emitting substance and has a first surface and a second surface constituting the surface opposite thereto, and a cathode which secures one end of the electron emitting film and comprises a first block and a second block respectively corresponding to the first surface and the second surface of the electron emitting film.

主权项

1. A field emission device comprising:
an electron emission film containing nano-sized electron emission materials and having a first surface and a second surface opposite to the first surface; a cathode comprising a first block and a second block corresponding to the first surface and the second surface of the electron emission film, respectively, to fix one end of the electron emission film; a substrate that supports the cathode; an anode formed on the other side of the substrate, facing to the electron emission film; and a gate formed between the cathode and the anode; wherein an overlap area of the first block for the electron emission film corresponds to that of the second block for the electron emission film, the overlap areas correspond to only the one end of the electron emission film, and the cathode, the anode and the gate are located in a same surface of the substrate.
