ABSTRACT:
It is the object of the present invention to provide a simple and accurate testing circuit and a testing method while occupying as small space as possible in an image display device. By partly changing dummy pixels arranged in the periphery of a display region into a testing circuit, tests for detecting broken wires in data signal lines and scanning lines and whether pixels are controlled adequately can be conducted easily and accurately, occupying as small space as possible without a need of an additional complicated circuit. Accordingly, a display panel can be produced at a low cost.
