ABSTRACT:
A field emission type display device has a structure in which each pixel is constituted of a combination of a plurality of small apertures and a plurality of small electron sources. Due to such a constitution, it is possible to reduce undesired impact of electrons on control electrodes and the enhancement of the heat resistance of the carbon nanotubes of electron sources, whereby it is possible to obtain a display device of high quality and long lifetime, while exhibiting a high-performance electron emission characteristic. Boron (B) is adhered to carbon nanotubes, which constitute electron sources, through the small apertures of the control electrodes; and, hence, the alignment of the small apertures and the small electron sources is ensured and the area of the electron source is set to be equal to or less than the area of the aperture.
