IPC: H01J31/12
Filed: 2003-05-28
Abstract: <P>PROBLEM TO BE SOLVED: To prevent field emission performance from being deteriorated, by enhancing adhesion of a lower electrode and a carbon material, suppressing uneven luminance in a picture element and between the picture elements, and enhancing heat resistance of the carbon material.  <P>SOLUTION: The carbon material is dispersed in a silica sol solution, and a solvent in the solution is removed by drying treatment.
