An active device array substrate including a substrate, a pixel array, and peripheral circuit is provided. The substrate has a display region and a peripheral region. The pixel array is disposed on the display region of the substrate, wherein the pixel array includes signal lines and pixels, each of the pixels is electrically connected to the signal lines respectively and extends from the display region to the peripheral region. The peripheral circuit is disposed on the peripheral region and includes a testing circuit electrically connected to the signal lines. Additionally, the testing circuit includes shorting bars and connecting conductors, wherein each of the signal lines is electrically connected to one of the shorting bars through one of the connecting connectors respectively, and at least two of the signal lines connected to the same shorting bar are electrically connected to each other through one of the connecting conductors.
