Abstract
There is provided a field emission type display which is capable of suppressing deterioration of image quality which otherwise occurs due to stepwise cuts and to the increase of wiring resistance caused by a thin width of a cathode line and which causes less failures. The display includes a plurality of cathode lines having an equal line width within the pixel and is structurally based on a multiple gradation representing a scheme of controlling spatial gradation display by changing the number of field emission type emitters to be driven by changing the number of cathode lines to be selected.
