Abstract
There is provided a display device including a high-sensitivity touch sensor. A display device includes: pixels arranged in a display region; sensing electrodes arranged in a sensing region; sensing lines coupled to the respective sensing electrodes; a noise detection electrode disposed on the same layer as the sensing electrodes; sensing channels each including a first input terminal coupled to any one of the sensing electrodes and a second input terminal coupled to the noise detection electrode, the sensing channels each generating an output signal corresponding to a voltage difference between the first and second input terminals; and a processor detecting a touch input, using the output signals of the sensing channels.
