Abstract

The invention provides a TFT (Thin Film Transistor) liquid crystal display device and a manufacturing method thereof. A common electrode line is enabled to have a vertical part and an extension part, wherein the vertical part is vertically intersected with gate lines and the extension part extends along the direction of the gate lines and is overlapped with the gate lines. Moreover, a TFT is enabled to have an I-shaped compensation channel structure in parallel with a data line. Therefore, the light transmission area of pixel areas is increased, the aperture ratio of a liquid crystal display is improved and the image display performance of the liquid crystal display is further improved.

Description

technical field [0001] The invention relates to the technical field of thin film transistor liquid crystal displays, in particular to a thin film transistor liquid crystal display device and a manufacturing method thereof. Background technique [0002] TFT-LCD (Thin film transistor liquid crystal display, Thin film transistor liquid crystal display) is a kind of liquid crystal display, which uses thin film transistor technology to improve image quality, and is widely used in TVs, flat panel displays and projectors. [0003] Since the cost of the source driver is higher than the cost of the gate driver, reducing the number of data lines (source lines) will reduce the cost of the driver. The liquid crystal display with dual gate wiring (dual gate) increases the number of data lines by half. 1 times the number of gate lines to reduce costs. [0004] Such as figure 1 As shown, the structure of the liquid crystal display with double gate wiring (dual gate) in the prior art incl...
