The present invention relates to a liquid crystal display (LCD) device. More particularly, the present invention relates to an LCD device including a thin film transistor (TFT) compensation circuit in an LCD device which implements a driving circuit by using an oxide TFT, the LCD device capable of compensating for degraded characteristics of a TFT due to threshold voltage shift. As the compensation circuit including a dummy TFT is formed on a non-active area of the LC panel, the degree of threshold voltage shift of the DT due to a DC voltage can be sensed. Based on the sensed result, a threshold voltage of a second TFT can be compensated. This can reduce lowering of a device characteristic.
