Abstract

A field emission display includes first and second substrates provided opposing one another with a predetermined gap therebetween; electron emission sources provided on one of the first and second substrates; an electron emission inducing assembly for inducing the emission of electrons from the electron emission sources; and an illuminating assembly provided on the substrate on which the electron emission sources are not formed, the illuminating assembly realizing images by the emission of electrons from the electron emission sources. The electron emission sources include a carbon nanotube layer and a base layer, the base layer connecting the carbon nanotube layer to the substrate and applying a voltage to the carbon nanotube layer required for the emission of electrons. Also, the carbon nanotube layer is provided on the base layer in a state substantially un-mixed with the base layer.

Description

technical field [0001] The present invention relates to field emission displays, and more particularly, to field emission displays including electron emission sources using carbon nanotubes. Background technique [0002] The first field emission displays used Spindt-type electron emission sources in which a material such as molybdenum or silicon was layered and sharp points were formed in multiple locations. However, the Spindt-type electron emission source complicates processing due to its fine structure, and requires high-precision processing. These factors make it difficult to apply the Spindt-type electron emission source to a display device having a large screen size. [0003] Accordingly, efforts are being made to simplify processing and facilitate production of display devices having a large screen size by forming flat electron emission sources using carbon-based materials. [0004] Carbon-based materials suitable for forming electron emission sources include graphi...
