Abstract: A display device includes: a gate transmission wiring; a gate insulating layer disposed on the gate transmission wiring; and a pixel electrode and a data transmission wiring that are disposed on the gate insulating layer. When a gate signal voltage is applied to the gate transmission wiring, the gate transmission wiring may serve as a gate electrode that activates a semiconductor layer. In addition, when such a gate signal voltage is not applied thereto, the gate transmission wiring may form an electric field by a voltage difference between the gate transmission wiring and the pixel electrode, to thereby control a liquid crystal layer.
