DEVICE AND METHOD FOR STICKING FLEXIBLE SUBSTRATE TO ANOTHER SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To extremely accurately adjust respective positions for sticking a flexible substrate to a transparent substrate on a liquid crystal panel with a simple constitution in a state of surely connecting electrodes formed at a fine pitch interval. SOLUTION: A transparent glass plate 17 is mounted on a receiving board 15, a through-hole 18 is formed on a position corresponding to two alignment marks formed on a liquid crystal panel 1 and an FPC 6, a telecamera unit 19 is arranged under the receiving board 15, and the alignment marks are observed through the through-hole 18 and the glass plate 17. The alignment mark formed on a transparent substrate 3 in a liquid crystal panel 1 is arranged on the upper position of the through-hole 18 and photographed by the telecamera unit 19 and the alignment mark of the FPC 6 in a state of being dropped from the receiving board 15 by a prescribed distance and depressed from the upper part of a press-welding head 20 is made to enter the visual field of the unit 19 through the through-hole 18.
