Abstract
Provided is a touch display device that can sense a touch input of a finger with the touch display device, recognize a finger touch position, specify a fingerprint sensing area, and sense a fingerprint in the fingerprint sensing area. Provided is also a touch display device that does not need a particularly fingerprint sensing line by performing fingerprint sensing using data lines of the touch display device and that can sense a fingerprint without decreasing a fingerprint sensing performance by minimizing a parasitic capacitance which can be generated in data lines, gate lines, touch electrodes, or the like at the time of sensing a fingerprint.
