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： A high-definition, high-quality, and high-contrast PDP that features high brightness, guaranteed long life, and stable driving, is provided by improving the time-dependent degradation of address discharge delay. The PDP includes: a front substrate having bus electrodes, and sustain discharge electrodes extending in a lateral direction of the bus electrodes to form display lines; a back substrate having address electrodes facing the sustain discharge electrodes in the lateral direction of the bus electrodes; and discharge cells formed between the substrates. Each of the discharge cells includes a sustain discharge cell and a priming discharge cell, in which a protruding electrode is formed to extend in a direction opposite to the discharge gap from the bus electrode, and a predetermined space is provided between the two cells to supply priming. The shape and size of the space are optimized so that the sustain discharge does not spread to the address discharge cell through the space.

摘要： The present invention provides an image display device which suppresses the generation of sparks between end portions of divided portions and an anode when data signal lines are divided in two. Within a display region, between scanning lines GAN, GB1, data signal lines are divided in two in one direction of the data signal lines, that is, into upper data signal lines DA and lower data signal lines DB. Assuming a width of the data signal lines DA, DB as W, and a distance between opposedly-facing end portions of the divided electrode portions as S, and a pitch of the data signal lines as P, by establishing a relationship S≦W/2, the influence of a potential attributed to an abnormal charge which concentrates on the end portion of the data signal line spreads radially and does not extend to a center portion of the divided portion thus suppressing an abnormal discharge.
