<P>PROBLEM TO BE SOLVED: To provide a mounting accuracy inspection method capable of detecting a relative location accuracy between a display panel and optical means at a low cost and at a high speed; and to provide an inspection device using the inspection method. <P>SOLUTION: A display device to be an inspection object includes a display panel disposed with a plurality of pixel groups, and an optical system for providing an image display from the pixel groups towards a plurality of N viewpoints (N is a natural number of 2 or more). The inspection device includes image output means for outputting an inspection pattern having image signals, which are different for every viewpoint, to the display device, and extraction means extracting a gradient and a position of a boundary segment of the inspection image displayed from the display device, and detects the location accuracy between the display panel and the optical means based on the gradient and the position extracted by the extraction means. <P>COPYRIGHT: (C)2012,JPO&INPIT |
