ABSTRACT:
A field emission display (100) includes a dielectric layer (132) having a plurality of emitter wells (134), a plurality of electron emitters (136) disposed one each within the plurality of emitter wells (134), a plurality of conductive rows (138, 140, 142) disposed on the dielectric layer (132) and having sacrificial portions (154), an ion shield (139) disposed on the dielectric layer (132) and spaced apart from the sacrificial portions (154) of the plurality of conductive rows (138, 140, 142), and an anode (121) opposing the plurality of electron emitters (136) and defining a projected area (122) at the plurality of conductive rows (138, 140, 142). The sacrificial portions (154) of the plurality of conductive rows (138, 140, 142) extend beyond the projected area (122) of the anode (121).
