<p><P>PROBLEM TO BE SOLVED: To provide an electron-emitting material having a large area for a display device which has superior electrical conductivity, thermal conductivity and the corrosion resistance of carbon material, and of which the work function is small, and to provide its manufacturing method. <P>SOLUTION: As the electron-emitting region, a graphite sheet 101 in which ions other than carbon are implanted into a prescribed region from surface, is fixed on a substrate 102 by an adhesive layer 103, a conductive gate layer 106 is installed via the graphite sheet and an insulating layer 105, and a phosphor layer 109 is arranged facing the graphite sheet 101. With this constitution, the electron-emitting material, which has superior characteristics of carbon material and of which the work function is small, is obtained, and a field emission element of high efficiency can be realized. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
