Abstract
An object of the present invention is to provide a paste for an electron emission source, which can retain good electric contact between CNT and a cathode electrode, by containing an electrically conductive particle having a particle diameter within the optimal range. A paste for an electron emission source containing a carbon nanotube having a diameter of 1 nm or more and less than 10 nm, and an electrically conductive part having an average particle diameter of 0.1 to 1 μm.
