Abstract

The invention discloses a liquid crystal display device and a repairing method thereof. The liquid crystal display device comprises an array substrate which is provided with a plurality of data wires, a plurality of scanning lines, a plurality of public electrode wires and a plurality of pixel electrodes, wherein a plurality of display units are spaced on the data wires, the public electrode wires and the scanning lines; two public electrode wires are arranged at a crossed area of each public electrode wire and each data wire; and the two public electrode wires are combined into one public electrode wire at the crossed area of each public electrode wire and each pixel electrode. With the design, the data wires can be repaired under the conditions of short circuit of the data wires and superposition of a short-circuit area and the scanning lines, and the problem that the scanning lines are broken after the data wires are repaired is solved.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device capable of repairing a short circuit of a data line and a corresponding repair method. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD) has gradually become the mainstream in the development of various display devices due to its thinness, energy saving, and environmental protection. [0003] figure 1 A display unit of a common twisted nematic (TN, Twist Nematics) type liquid crystal display device is given. The display unit is surrounded by data lines 102 arranged vertically, common electrode lines 101 and scan lines 107 arranged in parallel, and has a thin film transistor. The thin film transistor has a source 106, a gate 108 and a drain 104, wherein the source 106 is connected to the data line 102 , the gate 108 is connected to the scan line 107 , and the drain 104 is connected to the pixel electrode through ...
