1. An organic light emitting diode (“LED”) device, comprising:
a substrate;
a display unit comprising a plurality of thin film transistors (“TFT″s) and a plurality of organic LEDs on the substrate;
a pad on the substrate;
an encapsulation layer disposed on the substrate and comprising at least one inorganic layer and at least one organic layer;
a touch sensor disposed on the encapsulation layer and comprising connecting wires, first sensor electrodes and second sensor electrodes, the second senor electrodes being spaced apart from the first sensor electrodes in a plan view; and
a window cover above the touch sensor,
wherein the touch sensor is electrically connected to the pad via a contact hole in the display unit,
wherein one of the first sensor electrodes comprises a first portion and a second portion, the first portion mainly extending in a first direction in a plan view, the second portion mainly extending in a second direction intersecting the first direction in a plan view, and the first portion and the second portion being directly connected to each other at a point where the first portion and the second portion intersect,
wherein one of the second sensor electrodes comprises a third portion and a fourth portion, the third portion mainly extending in a first direction in a plan view and the fourth portion mainly extending in the second direction in a plan view,
wherein the second portion of the one first sensor electrode is disposed between a pair of organic LEDs directly next to each other in the first direction in a plan view,
wherein one of the pair of organic LEDs comprises a first side and a second side opposite to the first side, the first side facing the second portion of the one first sensor electrode in a plan view, and the second side facing the fourth portion of the one second sensor electrode in a plan view,
wherein the TFT comprises an active layer, a gate electrode, a source electrode, and a drain electrode,
wherein the first sensor electrodes, the connecting wires, the source electrode, and the drain electrode comprise metallic materials, and
wherein the first sensor electrodes and the source electrode, or the first sensor electrodes and the drain electrode comprise same materials.
