Abstract
The present disclosure provides a display device having a touch sensor for securing improved touch-sensing performance. The display device having a touch sensor includes a touch-driving circuit configured to drive a touch-driving line and a touch-sensing line, which are disposed on an encapsulation unit covering a light-emitting element, in a mutual-capacitance mode and to drive at least one of the touch-driving line or the touch-sensing line in a self-capacitance mode, and the touch-driving circuit supplies a load free driving signal to a shield line overlapping the touch-driving line and the touch-sensing line, thereby securing improved touch-sensing performance.
