  • Publication number: 20180102079
    Abstract: A thin film transistor array substrate, a manufacturing method thereof and a liquid crystal display using the same are provided. The array substrate includes an array substrate base, a thin film transistor (TFT) array layer, a color filter layer, a pixel electrode passivation layer, a pixel electrode connected with the TFT array layer through a via hole, and a patterned recessed microstructure disposed on a surface of the color filter layer. Thus, the patterned recessed microstructure is formed on the surface of the color filter layer through a mask forming the via hole without increasing the manufacturing cost, so that the volatiles generated by the process of the color resist and the subsequent high temperature process of the pixel electrode passivation layer are completely released to avoid gas residues, eliminate the possibility of bubbles in products in later period, and improve the quality of the product.
