Abstract
A system and a method for inspecting misalign between a display panel and a film patterned retarder (FPR) in the stereoscopic image display separating polarized lights of a left-eye image and a right-eye image using the FPR. The system for inspecting misalign between a display panel and a film patterned retarder includes: an inspection target panel including the display panel to which the film patterned retarder adheres; a misalign inspector for imaging edge images of both sides of the inspection target panel or imaging a central image of a pixel array of the inspection target panel; and a controller for analyzing an image received from the misalign inspector to measure a misalign degree between the film patterned retarder and the display panel.
