Claim:
1. A method for fabricating signal lines of a display device integrated with a touch screen panel, the method comprising: forming a thin film transistor on a substrate; sequentially forming a thin film transistor protective layer covering the thin film transistor, a first electrode layer and a conductive metal layer; etching the first electrode layer, the conductive metal layer and the thin film transistor protective layer by using a first photo-mask to form a first contact hole, through which a source electrode or a drain electrode is exposed, in the first electrode layer and the thin film transistor protective layer, and forming a first electrode and a touch signal line; coating a first electrode protective layer; coating photoresist by using a second photo-mask and forming a first electrode and a first touch connection pattern separated from the first electrode; and forming a second electrode and a second touch connection pattern made of the same material as that of the second electrode to be connected with the second electrode by using a third photo-mask, and at the same time, forming a first connection pattern, which connects one of either the exposed source electrode or the drain electrode with the first electrode through the first contact hole.
