Abstract: The present invention provides a display device capable of reducing cost by reduction in number of integrators. Signal lines (91 to 94, 95 to 98, 99 to 912, 913 to 916) are brought together into one line by means of signal lines (10a, 10b, 10c, 10d) to be connected to integrators (4a, 4b, 4c, 4d), respectively. Selector lines (71 to 74) orthogonal to the signal lines (91 to 916) are formed and connected to a selector driving circuit (3). An a-SiTFT (12) is formed at each of intersections: an intersection of the selector line (71) and the signal lines (91, 95, 99, 913); an intersection of the selector line (72) and the signal lines (92, 96, 910, 914); an intersection of the selector line (73) and the signal lines (93, 97, 911, 915); and an intersection of the selector line (74) and the signal lines (94, 98, 912, 916). The selector lines (71 to 74) are driven in sequence by the selector driving circuit (3) in the frame period.

Abstract: An electron source includes a cathode electrode having an emitter of conical shape. A first insulating film surrounds the emitter. A first extracting electrode disposed on the first insulating film draws out electrons from the emitter. A second insulating film is disposed on the extracting electrode and a focusing electrode is disposed on the second insulating film for focusing the electrons. The films and electrodes are hollowed to constitute a well surrounding the emitter, and the electrodes are applied predetermined voltages respectively to control the electrons emitted from the emitter. A disturbance that the voltage applied to the focusing electrode causes to the electric field around a summit of the emitter is suppressed. The electrode source may be made by determining a thickness of a masking material so that, when forming the conical emitter, an area occupied by the films deposited on the masking material in the well is smaller than the well when all the films have been completed.
