摘要：
The invention has an object of automating the inspection of cell-gaps of a liquid crystal display panel. An RGB image formed on the surface of a liquid crystal display panel (15) to be inspected is picked up with a CCD camera (17), and color non-uniformity is analyzed by an image processing unit (18), thereby to inspect the non-uniformity of the cell-gap.
