摘要：
The active matrix circuit comprises a protection circuit which protects an active element from static electricity. In the protection circuit, a TFT (switching element) is connected via a connection wire between gate wires (signal wires). The connection wire includes a cutoff part, and a mark representing the cutoff part is located. A middle point which is equally distant from two contact holes (connection points) closest to the connection wire is included in a range of the cutoff part. In a case where a defect occurs, the cutoff part of the connection wire connected to the TFT concerned with the defect is cut. The protection circuit is modified by the cutting. The cutoff part is away from the contact hole, thereby preventing an electrically conductive material which disperses from adhering to the contact hole.
