Abstract
A display substrate includes a pixel, a signal transmission line, a first insulating layer and a test signal input part. The pixel is on an insulating substrate. The signal transmission line is on the insulating substrate to transmit an image signal. The first insulating layer is on the signal transmission line. The first insulating layer has a contact hole through which the signal transmission line is partially exposed. The test signal input part is on the first insulating layer, and includes an extended portion and a test signal pad. The extended portion is electrically connected to the signal transmission line through the contact hole, and is extended toward a side of the insulating substrate. The test signal pad is electrically connected to the extended portion. Therefore, the number of defects is decreased.
