Abstract

The invention provides a liquid crystal display (LCD) device and a repairing method thereof. The LCD device comprises a display driver, an active area and a first signal wire, wherein the first signal wire is connected with the display driver and the active area, and the first signal wire has a defect. The repairing method of the LCD device comprises the following steps: 1. installing repairing wires between the display driver and the active area and on the first signal wire, wherein the repairing wires and the first signal wire are not communicated mutually, but are intersected and have at least two cross points, the repairing wire between the two cross points is continuous, the tow cross points are arranged on the two sides of the defect; and 2. shorting out the repairing wire at the two cross points and the first signal wire, and cutting off the first signal wire between the defect and the two cross points.

Description

technical field [0001] The present invention relates to a liquid crystal display device and its repairing method, in particular, the liquid crystal display device has a repair line for repairing the defect of the signal line between the display driver and the active area. Background technique [0002] In the conventional technology, during the manufacturing process of the liquid crystal display device, the signal line between the display driver and the active area (Active Area) is often short-circuited or open-circuited, which makes the panel unusable and increases the cost. [0003] Such as figure 1 In the liquid crystal display device 100 shown, a plurality of signal lines 106 are connected to the display driver 102 and the active area 104 on the panel 101 . As shown in the figure, if a defect occurs in one of the signal lines 106, the display driver 102 cannot provide a signal to the area 1042 corresponding to the signal line 106 in the active area 104 through the signal...
