The present invention relates to a touch panel liquid crystal display device capable of increasing the touch sensing performance by preventing the unbalance of touch raw data at left and right sides and a driving method thereof. According to the present invention, in the touch panel liquid crystal display device, a plurality of common lines disposed in a non-display area of a panel and detecting the characteristics of a panel are connected to an LFD signal line by an FPCB when the FPCB is attached. 본 발명은 좌우측 측면의 터치 데이터(Touch raw data)의 불균형 현상을 방지하여 터치 센싱 성능을 향상시킬 수 있는 터치 패널 액정표시 장치 및 그의 구동 방법에 관한 것으로, 본 발명에 따른 터치 패널 액정 표시 장치는, 패널의 비표시 영역에 배치되어 패널의 특성을 검사하기 위한 복수개의 공통 라인들이 FPCB 부착 시 상기 FPCB에 의해 LFD 신호 라인에 연결된 것이다.
