Abstract
A cold cathode field emission display is described. A key feature of its design is that each group of microtips that constitute a pixel is located on the same equipotential surface and a reliable ballast resistor is interposed between the equipotential surface and the cathode line which powers the pixel. An efficient method for manufacturing the display is also described.
