Abstract
A display substrate includes an insulating substrate, a thin-film transistor (TFT), a pixel electrode, a signal line and a pad part. The insulating substrate has a display region and a peripheral region surrounding the display region. The TFT is in the display region of the insulating substrate. The pixel electrode is in the display region of the insulating substrate and electrically connected to the TFT. The signal line is on the insulating substrate and extends from the peripheral region toward the display region. The pad part is in the peripheral region and electrically connects to the signal line. The pad part is formed in a trench of the insulating substrate and includes a region that extends into the insulating substrate. Therefore, the signal line may be securely attached to the insulating substrate.
