    Abstract: The sensor module includes a sensor substrate, a plurality of sensor electrodes, and a plurality of sensor wirings. The sensor substrate has a sensor region and a sensor frame region surrounding the sensor region. The plurality of sensor electrodes is located over the sensor region and is arranged in a plurality of rows and a plurality of columns. The plurality of sensor wirings respectively corresponds to the plurality of sensor electrodes, is electrically connected to the corresponding sensor electrodes, respectively, and each has a terminal over the sensor frame region. The plurality of terminals is arranged along a side of the sensor region. At least one of the sensor wirings connected to the sensor electrode includes a resistance-adjusting portion in each column. A resistance of the resistance-adjusting portion is higher than a resistance of another portion in the sensor wiring including the resistance-adjusting portion.
