Abstract: A display having hot electron type electron sources displaying an image by a line sequential scanning scheme is provided to prevent poor brightness uniformity along scan lines. The hot electron type electron source is provided with a top electrode bus line serving as a scan line and a bottom electrode bus line serving as a data line. The top electrode bus line has a sheet resistance lower than that of the bottom electrode. The wire sheet resistance of the scam line can be reduced to several m/square. When forming a 40 inch large screen FED using the hot electron type electron sources, a voltage drop amount produced in the scan line can be suppressed below an allowable range. As a result, high quality image without poor brightness uniformity can be obtained.

Abstract: There is provided a field emission electron source at a low cost in which electrons can be emitted with a high stability and a high efficiency and a method of producing the same. In the field emission electron source, a strong electric field drift part 106 is formed on the n-type silicon substrate on the principal surface thereof and a surface electrode 107 made of a gold thin film is formed on the strong electric field drift part 106. And the ohmic electrode 2 is formed on the back surface of the n-type silicon substrate 101. In this field emission electron source 110, when the surface electrode 107 is disposed in the vacuum and a DC voltage is applied to the surface electrode 107 which is of a positive polarity with respect to the n-type silicon substrate 101 (ohmic electrode 2), electrons injected from the n-type silicon substrate 101 are drifted in the strong electric field drift part 106 and emitted through the surface electrode 107. The strong electric field drift part 106 comprises a drift region 161 which has a cross section in the structure of mesh at right angles to the direction of thickness of the n-type silicon substrate 1, which is an electrically conductive substrate, and a heat radiation region 162 which is filled in the voids of the mesh and has a heat conduction higher than that of the drift region 161.
