Abstract

A touch display device includes a touch sensing electrode and a touch drive electrode disposed on an encapsulation unit configured to encapsulate a light-emitting element, the touch sensing electrode and the touch drive electrode being configured to form a first mutual capacitor, and first and second compensation electrodes disposed in a non-active area of a substrate so as to be opposite each other, the first and second compensation electrodes being configured to form a second mutual capacitor, whereby the value of capacitance of all mutual capacitors is increased, and therefore it is possible to prevent deterioration in touch performance.
