Abstract: Provided are a Liquid Crystal Display (LCD) device and a driving method thereof. A method of driving a liquid crystal display (LCD) device includes: transferring a pull-up signal to a corresponding gate line formed in an in-cell touch panel during an image output period in one frame and, after the pull-up signal is outputted during the image output period, turning on a first pull-down transistor or a second pull-down transistor to transfer a pull-down signal to the gate line; and detecting a touch by using a touch electrode formed in the in-cell touch panel while the stage turns on the first pull-down transistor and the second pull-down transistor to transfer the pull-down signal to the corresponding gate line, during a touch sensing period in the one frame, wherein, the stages sequentially transfer the pull-up signal to the respective gate lines.
