ABSTRACT:
A field emission type fluorescent display device capable of exhibiting high luminescence under a low voltage while minimizing leakage luminescence and color mixing, to thereby improve display quality. An anode and a field emission cathode are arranged opposite to each other and the cathode is divided into a plurality of unit regions in a matrix-like configuration, which are matrix-driven, resulting in a display being selectively carried out. The unit regions each are divided into a plurality of subregions and the cathode and anode are divided into a plurality of strip-like electrodes perpendicular to each other, respectively. The strip-like electrodes each correspond to each of subregions and are commonly connected to each other at every second interval. Also, a focusing electrode may be arranged between the gate and the anode so as to surround the unit regions.
