Claims
- 1. A field emission device comprising:
- an insulating substrate having a planar surface and a recess;
- a gate formed on said recess; and
- an emitter formed on said planar surface, said emitter having a pectinate shape including a plurality of rectangular tips of a predetermined pitch at a distal end thereof and said tips being formed substantially on a same plane with an edge of said gate when viewed from above so as to satisfy a relationship of b/a.gtoreq.2, wherein a represents an edge width of each of said tips and b represents an interval between each adjacent two of said tips.
- 2. A field emission device as defined in claim 1, wherein an area between each adjacent of said tips is formed into a predetermined curvature radius.
- 3. A field emission device as defined in claim 1, further comprising an electrode layer arranged on said emitter so that a distal end of said electrode layer is located at a position retracted from a distal end of said tips of said emitter.
- 4. A field emission device as defined in claim 1, wherein said tips are formed so as to satisfy the relationship of c/a=(b+a)/a=3, wherein c further represents the pitch of said tips.
- 5. A field emission device as defined in claim 1, further comprising a collector formed on said planar surface in a coplanar configuration with said emitter and spaced apart by said recess.
- 6. A field emission device as defined in claim 5, wherein said collector is provided with a phosphor.
