Abstract
A field emission display includes an insulating substrate, a number of first electrode down-leads, a number of second electrode down-leads, and a number of electron emission units. The first electrode down-leads are set an angle relative to the second electrode down-leads to define a number of cells and a number of intersections. Each electron emission unit is located at one of the plurality of intersections and in at least two adjacent cells. The electron emission unit includes a first electrode, a second electrode, and a plurality of electron emitters. The second electrode extends surrounding the first electrode. The plurality of electron emitters located on and electrically connected to at least one of the first electrode and the second electrode. A field emission display is also provided.
