摘要： PURPOSE:To establish a manufacturing method for a multi-layer connecting member which suits connection of a micro-circuit by using a solvent, in which the adhesive in the under-layer is not dissolved easily, to prepare the varnish constituting the adhesive in the over-layer when a multi-layer adhesive layer is formed, or using a material not easily soluble in the solvent of the over-layer to prepare the adhesive for the under-layer. CONSTITUTION:When a multi-layer adhesive layer is to be formed, a solvent in which at least the adhesive in the under-layer is not easily dissolved, is used to prepare a varnish constituting the adhesive for the over-layer-otherwise, a material not easily soluble in the solvent for the over-layer is used to prepare the adhesive for the under- layer. For the under-layer, concretely, a material which is soluble in methyl-ethyl ketone, acetone, ethyl acetate, etc., and not soluble in toluene, alcohol, n-hexane, etc., is used as adhesive, for example highpolymer rubber or highpolymer epoxy-for the over-layer, adhesive is used such as rubber of relatively low molecular weight, epoxy of middle molecular weight, etc., which is soluble in toluene, alcohol, n-hexane, etc. The intended multi-layer connecting member is fabricated by applying adhesive varnish one coat over another upon a base film followed by a drying process so that an adhesive layer of two or more plies is formed, wherein conductive particles should exist at least in one of the layers.

摘要： PURPOSE:To enhance a resolving power and to improve reliability of connection by uniformly dispersing conductive particulates formed by coating the surfaces of spherical polymer particulates having rugged shapes on surfaces with a metal and specifying the average grain size thereof to a specific range into an insulating adhesive. CONSTITUTION:The conductive particulates 5 having an average grain size of 2 to 20mum formed by coating the spherical polymer particulates having the rugged shapes on the surfaces with the metal are used for the anisotropically conductive and adhesive film formed by uniformly dispersing the conductive particulates 5 into the insulating adhesive 6. The rugged shapes on the surfaces of the particles are preferably such that the specific surface area of these spherical particles is about 1.3 to 5 times the truly spherical particles having the same average grain size. The film of 0.05 to 0.5mum of nickel, etc., is formed by an electroless plating method on such spherical polymer particles. The conductive particulates 5 formed in such a manner are added at 0.1 to 15 pts.wt. to 100 pts.wt. insulating adhesive. As a result, the reliability of connection to counter electrodes 2, 4 per 1 piece of the conductive particulate is enhanced and the anisotropically conductive and adhesive film having high fineness is obtd.

摘要： PURPOSE:To obtain high display quality and prevent picture quality from deteriorating regardless of repetitive use by setting the surface resistance of a surface where an electrostatic image is formed, between surfaces of the back insulating substrate of an electrophoresis display panel, to a specific value. CONSTITUTION:The back insulating substrate 101 is constituted by laminating and fixing a polyethylene terephthalate film 102 and a polyethylene terephthalate film 103 which is made conductive and adhered and fixed to a transparent substrate 105 such as a glass plate across spacers 104 so that the film 103 is on the side of the surface where the electrostatic image is formed, thereby forming a sealed space. A transparent electrode 106 is made of ITO, etc., and electrophoresis display liquid 107, obtained by suspending paraffin hydrocarbon as a dispersant, titanium dioxide as white particulates, blue dye, a stabilizer, etc., is charged in the sealed space to constitute the electrophoresis display panel. The surface resistance of the film 103 where the electrostatic image is formed with corona ions is 5X10 -5X10 . An image with a 5.5 contrast is obtained by this device, there is no image blur generated, and even when the device is used repeatedly, the image has neither display irregularity nor erasure defect.

摘要： PURPOSE:To improve the display quality by performing an alkali process for the surface of a transparent electrode which is formed on a transparent substrate. CONSTITUTION:The transparent substrate 6d where the transparent electrode 6C is formed is cleaned with a neutral cleaner and then washed away, and an ultrasonic wave cleaning process is carried out while the substrate is dipped in a solution prepared by dissolving an alkali processing agent in alcohol; and an ultrasonic washing process in distilled water is performed, then the substrate is dried under a vacuum, and the alkali process is carried out for the transparent electrode substrate. Then spacers 6b are sandwiched between the transparent electrode 6c and a back insulating substrate 6a and after lamination, both ends are sealed with epoxy resin 12. Electrophoresis dispersing liquid 7 is injected into the substrate, which is sealed with epoxy resin to obtain the electrophoresis display panel 6. The sticking of particulates on the transparent electrode surface is reduced and the display panel, therefore, has a high contrast and no decrease in the contrast. Consequently, the display quality is greatly improved.

摘要： PURPOSE:To stabilize a corona discharge, to improve display quality and to enhance long-term reliability by forming a conductive layer inert to zone on the surface of control electrodes. CONSTITUTION:A voltage is impressed to a corona wire 1 to generate corona ions and the corona ions are moved on an electrophoresis display panel 6 while controlling the passage of the ions in a through-hole 5 with a control circuit board 3 to selectively electrify the corona ions on the picture elements of the panel 6. An electrostatic image is thus formed and displayed. The display device is used by forming the conductive layer (e.g.; gold plating layer) inert to ozone on the surface of the upper control electrode 4 of the substrate 3. Thus, the generation of an insulating film on the surface of the electrode 4 by contamination and the electrification of the film by the corona ions to impair the stability of the corona discharge are prevented.
