An apparatus and a method for inspecting defects of a display device are provided to obtain images corresponding to plural inspection images through once scan using plural line scan cameras by using plural composite inspection images generated from plural inspection images, thereby significantly reducing an image obtaining time. A stage(310) is mounted with a display device(360) and reciprocates in a predetermined scan direction. Plural line scan cameras(320-1 to 320-n) are spaced from the stage as much as a predetermined distance as having a linear photographing area vertical to the scan direction, and spaced from each other along the scan direction. An inspection pattern generating unit(330) divides each of plural inspection images corresponding to the number of the line scan cameras based on the spaced distance between the line scan cameras, sequentially combines partial images located in a cross direction from an inspection image matrix configured with each of the divided inspection images in order to generate plural composite inspection images, and sequentially outputs each of the composite inspection image to the display device according to a movement amount of the stage. An image processing unit(340) detects defects of the display device based on each of the inspection images that each of the line scan camera obtains from the plural composite inspection images outputted to the display device. |
