Abstract:
1. A method of manufacturing a liquid crystal display device, comprising: preparing a first substrate including a first array region having a first active area and a second array region adjacent to the first array region having a second active area; forming a first seal material in a closed loop shape for surrounding the first active area in the first array region on the first substrate; forming a second seal material in a closed loop shape for surrounding the second active area in the second array region on the first substrate, the second seal material arranged apart from the first seal material; forming a peripheral seal material arranged outside the first and second array regions, the peripheral seal material having an air intake opening; forming at least one air intake opening in the peripheral seal material at a position facing a space formed between the first and second seal materials; arranging a second substrate on a surface of the first substrate in which the first and second seal materials and the peripheral seal material are formed in a vacuum chamber under vacuum state; applying a pressure to the first and second substrates by pressure difference between an atmospheric pressure of circumference which surrounds the first substrate and second substrate and an atmospheric pressure of the space between the first and second seal materials by introducing atmosphere into the vacuum chamber and the space between the first and second seal materials from the air intake opening; and attaching the first and second substrates by curing the first and second seal materials and the peripheral seal material.
