摘要:
A field emission type display device has a structure in which each pixel is constituted of a combination of a plurality of small apertures and a plurality of small electron sources. Due to such a constitution, it is possible to reduce undesired impact of electrons on control electrodes and the enhancement of the heat resistance of the carbon nanotubes of electron sources, whereby it is possible to obtain a display device of high quality and long lifetime, while exhibiting a high-performance electron emission characteristic. Boron (B) is adhered to carbon nanotubes, which constitute electron sources, through the small apertures of the control electrodes; and, hence, the alignment of the small apertures and the small electron sources is ensured and the area of the electron source is set to be equal to or less than the area of the aperture.

A display device that includes: a first substrate on which a second conductive layer to be stacked on a first conductive layer through an insulating layer is formed; a second substrate facing the first substrate; and a pillar-shaped spacer that holds the first substrate and the second substrate so that a gap between the first substrate and the second substrate is substantially uniform. The pillar-shaped spacer is disposed above the first conductive layer. The pillar-shaped spacer is disposed above the first conductive layer through a hole provided in the second conductive layer in a region where the first conductive layer and the second conductive layer are stacked through the insulating layer.

In a display device which includes a back substrate, a face substrate, a support body which is interposed between both substrates and surrounds a display region, thus forming an inner space, and a sealing material is provided which hermetically seals the support body and both substrates, thereby to provide a display device having a long lifetime and in which the desired degree of vacuum can be ensured in the inner space. A partition wall body is arranged substantially in parallel at the outside of the display region and at the inside of the support body, and getters are arranged in a space defined between the partition wall body and the support body.

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.

摘要:
Inside an outer frame, which is interposed at between opposedly facing peripheries between a back substrate and a front substrate, there is an inner frame which fixes both end portions of plate member control electrodes, which are constituted of a large number of parallel strip-like electrode elements. By integrally forming the plate member control electrodes such that the plate member control electrodes are fixed to both end portions of a display region, a single part is formed. Further, a getter chamber is formed between the outer frame and the inner frame and getters are accommodated in the getter chamber. Due to such a constitution, the operability and yield rate of products at the time of assembling can be enhanced. Further, it is possible to hold a desired degree of vacuum in the space between the substrates for a long time.
摘要:
To detect a dark current when an abnormal discharge occurs between an anode and respective electrodes, on an inner surface of a front substrate, a dark current detection electrode is formed in a state that the dark current detection electrode is positioned adjacent to the outside of a screen display region on which an anode is formed and on a plane substantially equal to a plane on which the anode is formed. Then, between an electrode terminal of the dark current detection electrode and a ground, an ammeter which detects the flow of a dark current and a DC power source having a preset voltage value which is more or less lower than a high voltage supplied to the anode are connected in series.

Using a cathode material with which an electron emission having sufficient intensity is obtained with a low electric field, over a back substrate, cathodes and first control electrodes are formed on the same plane, which is parallel to the back substrate, thus forming electron beam sources, and second control electrodes, which focus electrons taken out from the electron beam sources, are formed, whereby it is possible to obtain an image display of high brightness.
