Abstract
A display device includes a touch panel and a display panel. The touch panel outputs touch sensing signals. At least one of a plurality of touch sensing signals is converted from a time domain to a frequency domain, and then information on a thickness of a common electrode is detected based on a peak of the converted touch sensing signal. As a result, it is possible to inspect whether the common electrode is formed with a uniform thickness without destroying the display device.
