发明名称 METHOD AND DEVICE FOR MANUFACTURING LIQUID CRYSTAL DISPLAY ELEMENT
摘要 PROBLEM TO BE SOLVED: To enable adaptation to a large size to be required in future by improving display quality by increasing the alignment precision, gap precision, and in-gap-surface uniformity between a couple of substrates having liquid crystal between them. SOLUTION: In a variable pressure tank 8, a lower surface plate 10 which can freely be displaced in the horizontal direction while mounted with one substrate 2a, an upper surface plate 9 which can freely be displaced in the vertical direction while sucking the other substrate 2b, and a linear actuator 13 which drives the upper surface plate are installed. On the substrate 2a, a seal pattern sealing the liquid crystal is formed and liquid crystal is dripped by an amount which is large enough to fill a cell gap. On the substrate 2a or the other substrate 2b, spacers which prescribed a cell gap are scattered. In a pressure-reduced atmosphere, the upper surface plate 9 is displaced by the linear actuator 13 to bring one end part of the substrate 2a into contact with the substrate 2b and in this contact state, the upper surface plate 9 is turned to make the entire surface of the substrates come into contact with each other and then both the substrates are pressed and laminated together.
