Pastes for circuit connections and anisotropic conductive pastes that are excellent in storage stability and dispenser application properties, can be free of voids, bubbles and bleeding on thermocompression bonding and can give cured products having high bonding and connection reliability at high temperatures and high humidity, and the ability to be repaired. The paste for circuit connection contains an epoxy resin, an acid anhydride curing agent or a phenolic curing agent, and high-softening point fine particles. The anisotropic conductive paste additionally contains conductive particles. The method of using the paste for circuit connection or the anisotropic conductive paste involves connecting an electric circuit wiring formed on a substrate with an electric circuit wiring formed on another substrate with the paste for circuit connection or the anisotropic conductive paste.
摘要:
A cell gap uniformity in the vicinity of a seal and inside a display region of a liquid crystal display device is enhanced. Further, even when a multi-daylight press is used in a substrate bonding process, a variation in cell gap depending on the stratal positions of substrates is suppressed. In the process of bonding together two substrates on which display use electrodes are formed, the two substrates are bonded together with interposition of a seal member and a spacer. Thereafter, first, the bonded substrates are pressurized according to a specified pressurization profile in a normal temperature state of, for example, 26.degree. C., thereby extending the seal member. Subsequently, these substrates are pressurized according to a pressurization profile whose maximum pressure is set smaller than the maximum pressure in the normal temperature state with heat applied to the substrates, thereby hardening the seal member.
