Abstract
A display substrate includes a pixel electrode including a main electrode and a sub-electrode disposed apart from the main electrode and including an opening part. The display substrate includes a first switching device and a second switching device. The first switching device is connected to the main electrode. An extension electrode extends from the second switching device and overlaps the opening part. The extension electrode is connected to the sub-electrode via a contact part. According to the present invention, after a defective pixel is repaired, the repaired pixel operates normally.
