1. A thin film transistor panel comprising:

  • an insulating substrate having a display area and a surrounding area;

    a first signal line formed on the insulating substrate;

    a second signal line formed on the insulating substrate and insulated with and intersecting the first signal line to define the display area;

    a plurality of driving signal lines formed on the surrounding area of the insulating substrate and connected to a Voff voltage applying terminal;

    a plurality of inspection signal lines formed on the surrounding area of the insulating substrate;

    a first thin film transistor for inspection having a drain electrode coupled to the first signal line, a source electrode coupled to any one of the inspection signal lines and a gate electrode coupled to any one of the driving signal lines; and

    a second thin film transistor for inspection having a drain electrode coupled to the second signal line, a source electrode coupled to any one of the inspection signal lutes and a gate electrode coupled to any one of the driving signal lines.
