Abstract:
A display substrate includes a gate wire, a data wire which crosses the gate wire, a display part, a dummy pixel part and a test part. The display part includes a pixel element electrically connected to the gate wire and the data wire, and the pixel element includes a display element. The dummy pixel part surrounds the display part to protect the pixel element from static electricity. The test part is formed adjacent to the display part and includes a test element having a test display element formed in a substantially same manner as the display element.
