Abstract

PURPOSE: To accurately position a liquid crystal display panel by providing the positioning device with a correction mark display means for displaying a position correcting mark on a prescribed position of the display panel, a deviation calculating means and a position correcting means.
CONSTITUTION: A position correcting mark memory 17 is connected to a display controller 16 to store position correcting mark data and reference position data obtained when the liquid crystal display panel 1 is put on a prescribed inspection position on a driver board 2 are stored in a reference display mark memory 22. The deviation calculating part 23 receives the image data of the panel 1 which are stored in an image memory 21, executes image processing, calculates a deviation between the position of a correcting mark and that of a reference display mark, and sends a deviation correction control signal to an XY table controller 13 and a θ table controller 15. Consequently the panel 1 can be automatically and highly accurately positioned on the prescribed inspection position of the panel.
