PROBLEM TO BE SOLVED: To provide an inspection device which allows a display panel to be accurately inspected with reduced man-hours and the manufacturing cost thereof to be reduced.SOLUTION: An inspection device includes a first light source 4 for irradiating light to a display panel 2 having two reference holes 20 from the rear face of a base plate 21 so as to pass the light through a translucent part 22 and each of the reference holes 20, a second light source 5 for irradiating light to the display panel 2 from the front face of the base plate 21 so as to illuminate a non-translucent part 23, and a CCD camera 6 for photographing the display panel 2. A control panel 7 includes a storage part 7b which stores product data 75 of the display panel 2 created with CAD, a computing part 7a which computes a photographed image, and a determination part 7c which determines the printing state of the display panel in a state that on the basis of computing data 71 of the translucent part, computing data 72 of the non-translucent part, and computing data 73 of the two reference holes processed in the computing part 7a, the computing data 73 of both the reference holes conform to the positional data 75c of the reference holes of the product data 75, through the comparison among the product data 75, the computing data 71 of the translucent part, and the computing data 72 of the non-translucent part. |
