1. A sensor device comprising:
first sensors;
second sensors which forms a capacitance with the first sensors; and
a sensor driver which transmits driving signals to the first sensors through first sensor lines, and receives sensing signals from the second sensors through second sensor lines,
wherein the sensor driver sequentially transmits the driving signals to the first sensors, and transmits, during each period of transmitting the driving signals, an offset signal to at least one selected from the first sensors which does not receive the driving signals,
wherein the offset signal is identical in frequency to and different in phase from the driving signals, and
wherein the sensor driver sets at least one selected from a slew rate and a voltage level of the offset signal to a value different from a corresponding value of a corresponding driving signal.
