A light emitting display panel and a device light emitting display device including the same including a substrate, a thin film transistor disposed on the substrate layer and comprising a first active layer a first gate electrode and the first electrode pattern, a first insulating layer disposed on the thin film transistor, a conductive pattern disposed on the first insulation layer, a second insulating layer disposed on the conductive pattern, a first electrode disposed on the second insulating film, and contacted to the first electrode pattern, and a bank exposing a portion of the top surface of the first electrode, wherein the first electrode and the conducting pattern is used as an electrode of storage capacitor and the conducting pattern is overlapped with a top surface of the first electrode not overlapped with the bank.

Organic light emitting display panel and organic light emitting display device including the same

A display device comprises: a pixel array including pixels connected to gate lines; a gate driver that sequentially supplies scan signals to the gate lines by using a plurality of stages connected in cascade; and a driving voltage generator that supplies first and second driving voltages to the gate driver and inverts the first and second driving voltages of opposite phases at given intervals, wherein an nth stage (n is a natural number), among the stages of the gate driver, comprises: a start controller that charges a Qnode in a period when an (n&#x2212;1)th scan signal and a first clock signal are synchronized, and charges a QB node in a period when an (n&#x2212;1)th carry signal, opposite in phase to the (n&#x2212;1)th scan signal, and the first clock signal are synchronized; a first node controller that charges a Qnode or a QB node in response to a voltage at the Qnode; a first output control transistor that outputs an nth scan signal through a Q node in response to a voltage at the Qnode; and a second output control transistor that charges the Q node with the second driving voltage in response to a voltage at the QB node.
