Abstract
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.
