Disclosed is a liquid crystal display device in which a repair line can be substituted for a defective bus line by spot-fusing of a laser when a defect such as an open or a short between bus lines occurs in a lower substrate on which a plurality of thin film transistors are arranged in matrix, comprising a plurality of gate bus lines are spaced from each other and arranged in row direction on the lower substrate, each of the gate bus lines being connected to a corresponding gate pad for receiving an externally applied signal; a plurality of data bus lines spaced from each other and arranged in column direction on the lower to be intersected with the gate bus lines, each of the data bus lines being connected to a corresponding data pad 3a for receiving an externally applied signal; repair portion formed in outside portion of the lower glass substrate except a portion in which the thin film transistors connected to the gate and data bus lines are formed, and connected to a repair pad for receiving an externally applied signal, the repair portion having a first crossing portion between the repair portion and each of the bus lines and a second crossing portion between a first line extended from the repair portion and a second line extended from each of the bus lines.
