Abstract: A field emission cathode comprises at least one electron emitting parcel, and at least one ion absorbing parcel each being electrically connected with each of the at least one electron emitting parcel. The electron emitting parcel includes a first substrate and a nano emission component disposed on the first substrate for emitting electrons in an electric field. The ion absorbing parcel is constituted by a second substrate, in which the electric conductivity of the first substrate is less than that of the second substrate. A field emission light comprises the said field emission cathode, a field emission anode and a power supply. Thus the positive ions in an electric field can be absorbed by ion absorbing parcels to suppress an ion bombardment in the electric field. The efficiency of the electric field of the field emission is then maintained, and the lifetime of the field emission light is enhanced.
