An LCD is provided to effectively prevent image quality from being deteriorated by a leakage current of a transistor by always applying a low potential to a gate of the transistor. A liquid crystal panel includes a plurality of pixels defined by a plurality of gate lines and a plurality of data lines. A plurality of pads are formed in an outer edge region of the liquid crystal panel, and applies a signal to the gate lines and the data lines. A test pad is connected to the pad, and applies a test signal. A transistor(135) is installed between the pad and the test pad, and supplies a signal of the test pad to the pad as a signal applied thereto. An enable pad(130) is connected to a gate of the transistor, outputs an enable signal to turn on the transistor, and is connected to a low-potential terminal to apply a low potential signal to the gate of the transistor when the enable signal is discontinued. |
