METHOD AND DEVICE FOR ADHERING SUBSTRATE IN LIQUID CRYSTAL CELL MANUFACTURING PROCESS

摘要

PROBLEM TO BE SOLVED: To provide a method for adhering substrates suitable for manufacturing of a large sized liquid crystal cell.;SOLUTION: In the method for adhering a pair of substrates to each other with a prescribed call gap in a liquid crystal cell manufacturing process, (a) stuck substrates (1) having a spacer and an uncured thermosetting sealing material interposed between the pair of substrates are placed on a surface plate (2) and a flexible cover (3) is disposed on the surface plate 2, so as to cover the stuck substrate (1) to form a closed space (4) for housing the stuck substrates (1); (b) the closed space (4) is evacuated to press the stuck substrates (1) against the surface plate (2) via the cover (3) by the peripheral pressure; (c) the stuck substrates (1) are heated by heating means (4, 5) in a condition with the stuck substrates (1) being pressed against the surface plate (2) to cure the sealing material between the stuck substrates thermally; (d) the stuck substrates (1) are cooled by cooling means (7, 8) while maintaining the condition that the stuck substrates (1) are pressed against the surface plate (2) to adhere the stuck substrates to each other with the prescribed gap. The surface plate (2) is maintained in the same position during the stages of from (a) through (d).;COPYRIGHT: (C)2002,JPO
