It is an object of the present invention to provide a display device where expansion of a frame portion over a substrate, which results from formation of a lead wiring over an active matrix substrate, is minimally suppressed to realize a narrow frame. According to one feature of a display device of the present invention, a chamfer portion is formed at least at an end portion of an active matrix substrate having a pixel portion of a pair of substrates disposed to be opposed to each other, and wirings (a source line, a gate line, a storage capacitor line, a leading out wiring, and the like) over the active matrix substrate are electrically connected by a common wiring formed in the chamfer portion. 1. A display device comprising:a first substrate having a first chamfer portion at an end portion of the first substrate;a second substrate having a second chamfer portion at an end portion of the second substrate over the first substrate;a wiring formed over the first substrate; anda common wiring formed in contact with the first chamfer portion and the second chamfer portion,wherein the wiring is electrically connected to the common wiring.2. A display device according to claim 1 , wherein the common wiring is formed using a conductive material containing at least one of Ag claim 1 , Au claim 1 , Cu claim 1 , Ni claim 1 , Pt claim 1 , Pd claim 1 , Ir claim 1 , Rh claim 1 , W claim 1 , Al claim 1 , Ta claim 1 , Mo claim 1 , Cd claim 1 , Zn claim 1 , Fe claim 1 , Ti claim 1 , Si claim 1 , Ge claim 1 , Zr claim 1 , Ba claim 1 , and Nd.3. A display device according to claim 1 , wherein the common wiring is formed using indium tin oxide or indium zinc oxide.4. A display device according to claim 1 , wherein a connection portion to a driver circuit is formed on the first substrate.5. A display device according to claim 1 , wherein a third chamfer portion is formed on the first substrate.6. A display device according to claim 1 , wherein the display device further comprises a ...
