ABSTRACT:
An LCD 1 is evacuated from the focus range of the camera 4 in a horizontal direction, while a positioning object 18 on a TCP 17 is placed in the focus range of the visual field of the camera 4 to obtain a dislocation of the TCP 17 by monitoring the positioning object 18. The TCP 17 is then lifted in a vertical direction keeping its horizontal position until it goes out of the focus range of the camera 4. The LCD 1 is returned in the horizontal direction so that a positioning object 2 on the LCD 1 comes into the focus range of the camera 4. Then, a dislocation of the LCD 1 is detected by monitoring the positioning object 2. A mutual positional relation is corrected by shifting at least either the LCD 1 or the TCP 17 in the horizontal direction based on the detected dislocations of the positioning objects 2 and 18. Finally, the TCP 17 is lowered keeping its horizontal position, and mounted on the LCD 1.
