摘要： In a light emitting display device using electron emitter elements, it is possible to prevent lowering of image quality caused by spread of electron beams. MIM (Metal Insulator Metal) is used as the electron emitter elements and each of the electron emitter elements is surrounded by a conductive barrier (scanning wire). The electron emitter elements and the barriers are covered by upper electrodes so that the barriers and the surfaces of the electron emitter elements have the same electrical potential. The electron emitter elements and the barriers are formed on a cathode substrate. Color phosphors of R (red), G (green), and B (blue) are formed on an anode substrate at the side opposing to the cathode substrate. The color phosphors are excited by electron beams emitted from the electron emitter elements.

摘要： The present invention prevents a phenomenon that some electrons emitted from electron sources are charged to partition walls from influencing trajectories of the electrons thus preventing the shortage of excitation of phosphor layers. An image display device includes electron sources to which an electric current is supplied from scanning signal lines by way of current supply electrodes. The image display device also includes partition walls which are arranged on at least some of the scanning signal lines. Further, the current supply electrodes are connected with the electron sources on a downstream side of the scanning signal lines.

摘要： The present invention provides an image display device, in which a top electrode is selectively separated by laser ablation for each scan line. As the laser, a third harmonic wave of YAG laser with a wavelength of 355 nm is used. By setting film thickness of the interlayer insulator 15 to 100 nm and film thickness of a field insulator 14 to 140 nm, reflective spectrum has the minimum value near a wavelength of 355 nm, This laser beam is projected from a top electrode 13 toward a substrate 10. A part of the projected laser beam 20 is reflected by the top electrode 13, but most of the laser beam pass through a field insulator 14 and the interlayer insulator 15 and is reflected by a bottom electrode 11. As the result of interference of these two reflection waves, the minimum value appears in reflection spectrum. In this case, the laser beam is mostly absorbed near boundary surface between the top electrode 13 and the interlayer insulator 15. The top electrode 13 is processed by ablation (melting and evaporation), and the top electrode 13 is separated at this portion. By utilizing interference phenomenon in this manner, no damage is given to the interlayer insulator 13, the field insulator 14, and the bottom electrode 11, which serve as underlying layers, and the top electrode 13 can be selectively cut off.
