摘要： An image display device in which each pixel has a thin-film electron source composed of a lower electrode (which is a signal wire), an electron accelerating layer (which is formed by anodizing the surface of said signal wire), and an upper electrode (which covers said electron accelerating layer and releases electrons), in which the anodized film constituting said electron accelerating layer contains hydrated alumina component and anhydrous alumina component such that their ratio in the side close to the upper electrode is greater than that in the side close to the lower electrode. This structure prevents said thin-film electron source from being deteriorated in diode characteristics by said electron accelerating layer, thereby enhancing the reliability of said image display device.

摘要： For inhibiting generation of pixels that could not be displayed in a line in a display screen of an electron emission display comprising the pixels each provided with an electron source in which a first electrode at a signal line side and a second electrode at a scanning line side are joined through an isolating layer (electron acceleration layer), the present invention cuts off continuity between the first electrode and the second electrode which are short-circuited caused by a defect, so that the electron source with the defect is isolated from other electron sources. In the electron source with a defect, for example, a portion of the second electrode surrounding the above-mentioned defect thereof is excised by laser.

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.
摘要翻译：本发明提供一种图像显示装置，其中通过每个扫描线的激光烧蚀选择性地分离顶部电极。作为激光器，使用波长为355nm的YAG激光器的三次谐波。通过将层间绝缘体15的膜厚设定为100nm，将场绝缘体14的膜厚设定为140nm，反射光的波长为355nm附近的最小值。该激光从顶部电极13朝向基板 10。投射的激光束20的一部分被顶部电极13反射，但大多数激光束通过场绝缘体14和层间绝缘体15并由底部电极11反射。作为这两个反射波的干扰的结果，最小值出现在反射光谱中。在这种情况下，激光束主要在顶部电极13和层间绝缘体15之间的边界面附近被吸收。顶部电极13通过消融（熔化和蒸发）进行处理，顶部电极13在该部分分离。通过以这种方式利用干涉现象，不会对作为下层的层间绝缘体13，场绝缘体14和底电极11以及顶电极13进行选择性地切断。

摘要： An upper bus electrode is formed as a laminated wire of a metal film lower layer, a metal film intermediate layer and a metal film upper layer. Al lower in electrode potential is used as a low resistance material for the metal film intermediate layer of the upper bus electrode, while Cr high in heat resistance and oxidation resistance and higher in electrode potential than Al is used for the metal film lower and upper layers disposed as upper and lower layers. Al and Cr are selectively etched so that the metal film lower layer projects on one side and has an undercut on the other side with respect to the metal film intermediate layer. Thus, when the upper bus electrode has a structure using a laminated wire made of metal high in heat resistance and oxidation resistance, and metal low in resistance and sandwiched in the metal high in heat resistance and oxidation resistance, so as to separate an upper electrode from upper electrodes by self-alignment, deformation of the undercut portion due to oxidization of a side surface of the low-resistance metal is suppressed to improve the self-alignment separation characteristic of the upper electrode.
摘要翻译：上部总线电极形成为金属膜下层，金属膜中间层和金属膜上层的层叠线。电极电位的低电位被用作上部总线电极的金属膜中间层的低电阻材料，而与Al相比，耐热性和抗氧化性高，电极电位高的Cr用于金属膜下层和上层作为上层和下层排列。 Al和Cr被选择性地蚀刻，使得金属膜下层在一侧突出，并且在金属膜中间层的另一侧具有底切。因此，当上部总线电极具有使用由耐热性和抗氧化性高的金属制成的层叠线的结构，并且具有低电阻的金属并且被夹在金属中的耐热性和抗氧化性高的结构时，分离上电极通过自对准从上部电极，抑制由于低电阻金属的侧面的氧化引起的底切部分的变形，从而提高上部电极的自对准分离特性。

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： In a matrix electron emitter display using a thin-film electron emitter, a required resistance value of a top electrode, which value is determined by voltage drop at the top electrode, is small, and selection of a material and film thickness of the top electrode have been limited. Use of cathode structure which improves the capability of feeding from a feeding line to a thin-film electron emitter element improves the electron emission efficiency, and permits achieving higher luminance and lower power of a display apparatus.

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.
