Abstract:
1. A field emission plane light source comprising: an anode comprising an anode substrate, an anode conductive layer formed on a surface of the anode substrate, and a fluorescent layer formed on the anode conductive layer; and a cathode comprising a cathode substrate facing and separated from the anode substrate, a cathode conductive layer formed on a surface of the cathode substrate, and an electron emission layer formed on the cathode conductive layer and facing the fluorescent layer of the anode; the cathode and anode substrates forming a sealed chamber therebetween; and the electron emission layer comprising a glass matrix and a plurality of carbon nanotubes, metallic conductive particles electrically connecting the cathode conductive layer with the carbon nanotubes, and getter powders dispersed within the glass matrix.
