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 pixel units. The first electrode down-leads are set an angle relative to the second electrode down-leads to define a number of cells. Each pixel unit is located in each cell and includes a cathode electrode, an electron emitter, an anode electrode, and a phosphor layer. The electron emitter is electrically connected to the cathode electrode. The anode electrode has a bearing surface inclined to the insulating substrate. The phosphor layer is located on the bearing surface.
