Abstract:
1. A lower substrate comprising: a first signal electrode disposed in a circuit area; a first insulating layer having an opening, through which the first signal electrode is exposed; a second signal electrode disposed on the first insulating layer in the circuit area, and spaced apart from the first signal electrode; a second insulating layer disposed on the first insulating layer, the second insulating layer including a first contact hole, through which the first and second signal electrodes are exposed; a third insulating layer disposed on the second insulating layer, the third insulating layer including a second contact hole, through which the second insulating layer adjacent to the first contact hole and the first and second signal electrodes are exposed; and a conductive layer electrically connecting the first signal electrode to the second signal electrode through the first and second contact holes.
