Abstract: The present disclosure provides a touch display device for preventing deterioration in touch performance. The touch display device includes touch electrodes formed so that surfaces thereof that face the vertices of an emission area of a light-emitting element are formed in a rounded shape, thereby making the spacing distances between the touch electrodes and the emission area constant regardless of the positions thereof. The touch display device includes a light-emitting element disposed in an emission area having a plurality of vertices, an encapsulation unit disposed on the light-emitting element, and touch electrodes disposed on the encapsulation unit so as to surround the emission area. Accordingly, it is possible to eliminate the difference between viewpoints at which color shift occurs depending on the viewing direction.
