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.

Abstract: A pixel of a light emitting display device includes: a switching transistor which transfers a data voltage in response to a gate writing signal, a storage capacitor which stores a storage voltage, a driving transistor which generates a driving current based on the storage voltage stored in the storage capacitor, an emission transistor which selectively forms a path of the driving current in response to an emission signal, a light emitting diode which emits light based on the driving current, and a diode initialization transistor which transfers an initialization voltage to the light emitting diode in response to the emission signal. The storage voltage corresponds to a value obtained by subtracting a threshold voltage of the driving transistor from the data voltage.
