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.

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.

摘要： The present invention provides an image display device, by which it is possible to prevent oxidation of a terminal in anodic oxidation processing of a bottom electrode (data line) to make up a thin-film type electron source, to improve production yield and high reliability, and to increase the thickness of an interlayer insulator formed at the same time. A resist pattern 18 to form a terminal 40A of data line is limited to the bus line of the terminal 40A. Width of the resist pattern 18 is set to a value approximately equal to a value of the width of the bus line of the terminal 40A so that the resist pattern may not be present on the glass substrate, which is positioned between bus lines. The resist pattern is discontinuously formed by providing a slit 18A in extending direction of the bus line of the terminal 40A. The size of the resist pattern 18 is set to a value to match the width of the electron source based on the above results.
