摘要： 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.

摘要： The invention provides a display device using thin film type electron sources having a structure that can be formed in a simple manufacturing process. A lower electrode, a protective insulating layer and an interlayer film are formed on a cathode substrate. An upper bus electrode made from a laminated film of a metal film lower layer and a metal film upper layer is provided further on the interlayer film. A film of an upper electrode of a thin film type electron source for each pixel constituted by an insulating layer serving as an electron accelerating layer on the lower electrode and the upper electrode is formed on two stripe electrodes of the upper bus electrode in that pixel and another upper bus electrode in an adjacent pixel by sputtering. Then, the upper electrode is separated by self-alignment due to a setback portion of the metal film lower layer and an appentice of the metal film upper layer of the corresponding upper bus electrode. Thus, a thin film type electron source separated in accordance with each pixel is formed.

摘要： In a cathode substrate of an FED, spacers lines exclusive for connecting spacers to the ground were necessary besides scan lines and data lines, and a cathode substrate having a three-layer line structure was used in the prior art. The present invention realizes a high-reliable cold cathode type flat panel display which is easily produced and keeps performance that can be obtained by the three-layer line structure, using a cathode substrate having a two-layer line structure.The line structure of a cathode substrate (10) of an FED is made into a two-layer structure. Hitherto, lines of the first layer are bottom electrodes (11) which constitute electron sources and have been used as scan lines, and top electrodes (13) of the second layer have been used as data lines. In the present invention, however, the bottom electrodes (11) and the top electrodes (13) are changed to data lines and scan lines, respectively. Moreover, some parts of top electrode bus lines connected to the top electrodes (13) are used as spacer lines, too, or the top electrode bus lines (16) are divided so as to be made into spacer lines (16′).

摘要： As the top electrode material of a thin-film electron emitter, a material having a bandgap wider than that of Si and electrical conductivity is used. In particular, a conductive oxide such as an SnO2 or ITO film and a wide-bandgap semiconductor such as GaN or SiC are employed. The electron energy loss in a top electrode through which hot electrons pass can be reduced so as to enhance the electron emission efficiency. A high emission current can be obtained in the case of the same diode current as a prior art. In addition, in the case of the same emission current density as a prior art, a small driving current is enough. A bus line and driving circuits can be simplified.
