Abstract:
1. An inspection substrate for a display device, comprising: plural scan lines and plural signal lines, which are arranged to intersect each other; plural storage capacitor lines arrayed with the scan lines; storage capacitor elements, each of which uses a part of the storage capacitor line as one of electrodes thereof; storage capacitor upper electrodes formed of the same layer as a layer for the signal lines and electrically connected to the storage capacitor elements; switching elements arranged on intersection points of the signal lines and the scan lines and electrically connected to the storage capacitor elements; and dummy wiring lines formed by use of at least one of two types of metals constituting electrodes of the switching elements, and electrically connected to any of the storage capacitor lines, the signal lines and the storage capacitor upper electrodes; and dummy electrodes arranged corresponding to each of the switching elements, electrically connected to the scan lines, and configured to be used as contact pads for receiving a probe of a tester.
