1. A light emitting diode display device comprising:
a display substrate;
a light emitting diode disposed over the display substrate, the light emitting diode including a first electrode and a second electrode;
a pixel electrode electrically connected to the first electrode, the pixel electrode including a conductive material;
a common electrode electrically connected to the second electrode;
a driving transistor disposed over the display substrate, the driving transistor including an active layer, a source electrode, a drain electrode, and a gate electrode;
a relay electrode electrically connecting either the source electrode or the drain electrode to the pixel electrode; and
a first touch sensor electrode spaced apart from the light emitting diode, the first touch sensor electrode including the same conductive material as the pixel electrode
wherein the display substrate comprises an active area in which an image is displayed, the active area comprising:
a display circuit area;
a core pixel area located in the display circuit area and allowing the light emitting diode to be disposed;
a first power supply area located outside of the display circuit area and allowing a first power line to be disposed;
a second power supply area located outside of the display circuit area and allowing a second power line to be disposed; and
a gate driving circuit area located outside of the display circuit area and allowing a gate driving circuit to be disposed.
