摘要： A carbon nanotube has a carbon network film of polycrystalline structure divided into crystal regions along the axis of the tube, and the length along the tube axis of each crystal region preferably ranges from 3 to 6 nm. An electron source includes a carbon nanotube having a cylindrical shape and the end of which on the substrate side is closed and disposed in a fine hole. The end on the substrate side of the tube is firmly adhered to the substrate. The carbon nanotube is produced by a method in which carbon is deposited under the condition that no metal catalyst is present in the fine hole and produced by a method in which after the carbon deposition the end of the carbon deposition film is modified by etching the carbon deposition film using a plasma. Therefore, an electron source excellent in the evenness of field emission characteristics in a field emission region (pixel) in the device plane and driven with low voltage can be provided, and a display operated with ultralow power consumption exhibiting ultrahigh luminance can be provided.

摘要： Disclosed is a cold cathode electron source characterized in that a cold cathode material which can achieve electron emission in a low electric field (e.g., a carbon nanotube), necessary constituent elements are provided individually in uncalcined ceramic sheets (green sheets 21, 43, 46) and the sheets are laminated and calcined to form an integral structure. The electron source can be manufactured by forming through-holes 20 in a flat plate, charging a conductive paste 30 containing carbon nanotubes 31 dispersed therein into the through-holes 20 by vacuum suction, thereby causing to orient the carbon nanotubes 31 in the axis direction of the through-hoes 20. The electron source is useful for the low-cost manufacture of a device with a cold cathode electron source which can achieve ready vacuum evacuation and maintenance of the vacuum level, as well as a high emission current density at a low voltage.

摘要： A liquid crystal panel (9) includes a front substrate (1a) and a back substrate (1b), and a liquid crystal layer (3) provided between these substrates. A seal (4) is used to bond the front substrate (1a) and the back substrate (1b) together. A region where either of the pair of substrates is in contact with the liquid crystal layer (3) is divided into a display region (6) and a non-display region (5). The number of spacers (2) per unit area is larger in the display region (6) than in the non-display region (5). In other words, the density of the spacers (2) is different between the display region (6) and the non-display region (5), and the density of the spacers (2) is higher in the display region (6) than in the non-display region (5). According to this configuration, the display region (6) cannot be deformed significantly even under pressure from outside, and thus the non-display region (5) is deformed by the pressure.

摘要： The electron-source array of the present invention is provided with cathode electrodes placed on an insulation substrate in the form of lines; and gate electrodes that are placed face to face with the cathode electrodes with the insulation film being interpolated in between. In this arrangement, the cathode electrodes and the gate electrodes are arranged so as to intersect each other with a pore being formed at an intersecting portion between each cathode electrode and each gate electrode in a manner so as to penetrate the insulation film, and the pore is filled with a conductive material or a semiconductive material with the material being electrically connected to the corresponding cathode electrode, and is formed in a manner so as to separate from the gate electrodes with a space in between. Thus, it becomes possible to form very fine emitters uniformly without the need for a high-precision patterning technique and consequently to provide an electron-source array that enables an X-Y matrix driving process.
