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.
