Abstract

The invention relates to a liquid crystal display device and a repair method thereof. The liquid crystal display device comprises data wires, scanning wires, and terminal parts of the data wires, wherein the data wires and the scanning wires are mutually and vertically arrayed; and the terminal parts of the data wires are connected with the data wires. The liquid crystal display device also comprises first repair wires and second repair wires, wherein the first repair wires are vertically arrayed with the data wires; and the second repair wires are parallely arrayed with the data wires. The liquid crystal display device and the repair method can shorten the trace length of the repair wires and reduce the resistance and the capacitance of the repair wires.

Description

technical field [0001] The invention relates to a liquid crystal display device and a repair method thereof, in particular to a liquid crystal display device and a repair method thereof which reduce the resistance and capacitance of repair lines. Background technique [0002] The thin film transistor liquid crystal display (Thin Film Transisitor Liquid Cyrstal Display, TFT-LCD) has gradually become the mainstream of the current development of various display devices due to its thinness, energy saving, environmental protection and other characteristics. [0003] One side of the TFT-LCD array substrate is densely covered with many data lines, and the disconnection of each data line will cause line defects on the TFT-LCD panel, thereby affecting the qualified rate of the product. So far, many design methods for repairing wires have been proposed for repairing data wires after they are disconnected. figure 1 The first representative data line repair method in the prior art is g...
