To provide an inspecting device and a manufacturing method for a plasma display panel rear plate which can perform image processing by selecting and switching some of plural video signals, reduce the number of expensive image processors and the memory capacity in the image processors, lower the device cost, facilitate replacing operation in maintenance by decreasing the wiring quantity of a movable part, and perform inspection with high precision.
This is a device which inspects a fluorescent body on the plasma display panel rear plate and has an ultraviolet-ray irradiating means which irradiates the fluorescent body with ultraviolet rays, one or more color image pickup means which have photodetecting elements linearly arrayed, a video signal switching means which selects a specific video signal out of video signals outputted from the image pickup means, and a processing means which calculates the video signal outputted from the video signal switching means by the pixels; and the processing means compares the video signal with a specific reference value and inspects the plasma display panel rear plate according to the difference from the reference value.
