ABSTRACT:
A flat panel display device having formed on a drive substrate, a logic circuit for combining a first inspection-use output of a horizontal scanning circuit and a second inspection-use output of a vertical scanning circuit and a combined inspection-use output terminal for outputting the combined inspection-use output obtained through the logic circuit. Another flat panel display device of the present invention has switch circuits for using a first input terminal of the horizontal scanning circuit as an inspection-use output terminal of the vertical scanning circuit and using a second input terminal of the vertical scanning circuit as an inspection-use output terminal of the horizontal scanning circuit.
