Abstract

The invention discloses a thin film transistor liquid crystal display device and a signal line thereof. The signal line comprises a metal layer and a transparent conductive layer stacked on the metal layer, and the transparent conductive layer is electrically connected with the metal layer. A multilayer structure formed by the metal layer and the transparent conductive layer can reduce impedance of the whole signal line, resistance-capacitance delay of a circuit is reduced, and the charging rate is improved.

Description

【Technical field】 [0001] The present invention relates to a thin film transistor liquid crystal display, in particular to a thin film transistor liquid crystal display device with low impedance signal line and its signal line. 【Background technique】 [0002] Thin-Film Transistor Liquid Crystal Display (TFT-LCD) is a kind of display, because it has the advantages of low power consumption, thinness, high resolution, etc., so it is the mainstream of display at present. [0003] The signal lines on the pixel array substrate of the thin film transistor liquid crystal display often cause RC delay due to the existence of parasitic resistance and parasitic capacitance. For a small-sized liquid crystal display, the effect of resistance-capacitance hysteresis on the data transmission speed of the signal line is still negligible. However, as the size of the liquid crystal display device becomes larger, the length of the signal lines on the pixel array substrate also increases due to t...
