| description | The present invention relates to a touch panel liquid crystal display device and a driving method thereof, which increase touch sensing performance and reduce EMI noise. According to the present invention, the touch panel liquid crystal device comprises: a thin film transistor array substrate having a gate line, a data line and a common electrode; a color filter array substrate having a black matrix layer and a color filter layer; and an ITO film composed of a plurality of blocks formed on the color filter array substrate for touch sensing. A scan signal, a data signal and a common voltage are applied respectively to the gate line, the data line and the common electrode for a display period. The ITO film composed of the blocks is grounded. An LFD signal is applied to the gate line, the data line and the common electrode for a touch sensing period. The LFD signal is sequentially applied to the ITO film composed of the blocks.
