Abstract
The present disclosure provides a touch sensor embedded light emitting diode display device and a touch display panel. The device includes a substrate, a light emitting diode (LED) disposed over the substrate. The LED includes a first electrode and a second electrode. The device includes a pixel electrode electrically connected to the first electrode and a common electrode electrically connected to the second electrode. The device includes a driving transistor disposed over the substrate. The transistor includes an active layer, a source electrode, a drain electrode, and a gate electrode. The device includes a relay electrode electrically connecting the source electrode or drain electrode to the pixel electrode. The device includes a first touch sensor electrode disposed spaced apart from the light emitting diode and including the same conductive material as the pixel electrode.
