Abstract:
1. A thin film transistor substrate divided into a display area to display the image and a non-display beside the display area, the thin film transistor substrate comprising: first and second gate driving chips and a data driving chip on the non-display area; a common voltage line for an MPS (mass production system) test and a grounding line for the MPS (mass production system) test formed on the non-display area in parallel; an insulating layer to cover the common voltage line for the MPS test and the grounding line for the MPS test; and an electrode layer formed on the insulating layer corresponded to the common voltage line for the MPS test and the grounding line for the MPS test, wherein the common voltage line for the MPS test, the insulating layer and the electrode layer forms a first capacitor, and the grounding line for the MPS test, the insulating layer and the electrode layer forms a second capacitor.
