Title:
光学表示デバイスの生産システム及び光学表示デバイスの生産方法
Document Type and Number:
Japanese Patent JP5804404
Kind Code:
B2
Abstract:
An optical display device production system including: a stage (39) for supporting a liquid crystal panel (P); an unwinding unit (31a) for unwinding an optical member sheet (F1); a control device for acquiring data about the optical axis in-plane distribution of the optical member sheet (F1), and adjusting the cutting direction; a first cutting device (31b) for cutting the optical member sheet (F1) larger than a display region (P4); a detaching unit (31c) for detaching a sheet piece (F1m) from a separator sheet (F3a); a bonding head (32) for holding the sheet piece (F1m), and tilting; a drive device for causing the bonding head (32), and the table (39) to move relative to one another such that the cut side of the sheet piece (F1m), and one side of the liquid crystal panel (P) coincide, or are parallel; a detection device for detecting the outer peripheral edge of the bonding surface of the sheet piece (F1m) and the liquid crystal panel (P); and a second cutting device (50) for cutting apart the section of the sheet piece (F1m) that opposes the bonding surface, from a surplus section which is at the outer side of the opposing section.
