Discussed is a display device and a driving method thereof. The driving method includes respectively receiving a plurality of sensing signals from a plurality of touch electrodes formed at a touch panel, determining whether there is a normal touch, by using a size of a touch region defined by the received sensing signals, and when it is determined that there is the normal touch, performing an operation of extracting touch coordinates of the touch region, or when it is determined that there is an abnormal touch, performing an operation of receiving the sensing signals without performing the operation of extracting the touch coordinates.
