Abstract: A liquid crystal display device is provided. The liquid crystal display device includes a driving circuit; a lower insulation layer; an upper insulation layer; and an inorganic insulation layer. The driving circuit is disposed in a bezel area on a lower substrate. The lower insulation layer includes a lower opening through which an inorganic layer on the lower substrate is exposed and the lower opening is located at an outer side of the lower substrate than the driving circuit. The upper insulation layer is disposed on the lower insulation layer and includes an upper opening corresponding to the lower opening. The inorganic insulation layer is disposed on the upper insulation layer and in direct contact with the inorganic layer on the lower substrate so as to minimize damage to the driving circuit caused by infiltration of moisture from the outside.

Abstract: A display panel includes pixels connected to gate lines, and a gate driver that supplies a gate signal to at least one of the gate lines and includes a plurality of stages. Each stage includes a pull-up transistor to apply a turn-on voltage of a first clock signal to an output terminal responsive to a voltage at a Q-node, a pull-down transistor to apply a turn-off voltage to the output terminal responsive to a voltage at a QB-node that holds the turn-on voltage during a period in which the output terminal is applied the turn-off voltage, and a QB-node control unit to apply the turn-on voltage to the QB-node responsive to the first clock signal and a second clock signal in reverse-phase with the first clock signal. Accordingly, a display panel may include a gate driver that can set, reset, and hold the voltage at a QB-node.
