A laser repair structure of a LCD device obtained by extending dummy metal patterns of the LCD device is used to solve an abnormal color display. The structure includes a first electrical repair layer extending form a dummy metal to a first laser repair location; a second electrical repair layer extending form the dummy metal to a second laser repair location; a third electrical repair layer extending form a first source/drain electrode to the first laser repair location, a first dielectric layer provided between the third electrical repair layer and the first electrical repair layer; and a fourth electrical repair layer extending form a second source/drain electrode to the second laser repair location, the dielectric layer being also provided between the fourth electrical repair layer and the second electrical repair layer. The electrical repair layer is connected electrically with the third electrical repair layer after a first laser beam is irradiated to the first laser repair location, and the second electrical repair layer is connected electrically with the fourth electrical repair layer after a second laser beam is irradiated to the second laser repair location.
