ABSTRACT:
An inspection apparatus and inspection method for liquid crystal display devices are disclosed, wherein a final inspection for completely manufactured liquid crystal display devices is performed using a visual-light inspection apparatus, whereby high productivity due to improved inspection accuracy and reduced inspection time can be accomplished. With the inspection apparatus and inspection method, defects of a plurality of glass panels can be automatically inspected based on analyzed information of an entire screen of each glass panel using a plurality of vision cameras, whereby improved inspection accuracy and improved product quality can be accomplished and reduced inspection time can result in improved productivity of liquid crystal display devices. Further, by quantifying screen defects of the plurality of glass panels, defects of glass panels due to failures of manufacturing processes or design failures and other problems attendant on the defects can be prevented.
