preparation example Construction

[0082] The preparation process of the TFT-LCD array substrate of this embodiment is basically the same as that of the aforementioned first embodiment. Including the pattern of the first via hole 21, the second via hole 22 and the third via hole 23, the pattern comprising the pixel electrode 13 and the fourth connecting bar 17 is formed in the last patterning process, and the pixel electrode 13 passes through the first via hole 21 and the third via hole 23. The drain electrode 7 is connected, and the fourth connecting bar 17 connects the lower end of the data line 12 on one side of the pixel area with the upper end of the data line 12 on the other side of the pixel area through the second via hole 22 and the third via hole 23 In other words, the data lines of the same pixel column in this embodiment have a mirror-symmetrical structure.

Abstract

The invention relates to a TFT-LCD (Thin Film Transistor Liquid Crystal Display) array substrate and a manufacture method thereof. The array substrate comprises grid lines and data lines which are formed on the substrate, wherein pixel electrodes and thin film transistors are formed in pixel regions limited by the grid lines and the data lines; and the data lines have a mirror symmetry structure ensuring that the coupling capacitances of upper and lower adjacent pixel regions generate opposite changes. In the invention, the data lines are set to be the mirror symmetry structure, and when the pixel electrodes have shifts, because of the mirror symmetry structure of the data lines, the coupling capacitances Cpd of the upper and the lower adjacent pixel regions can generate mutually oppositechanges, thereby eliminating macroscopic uneven conditions on the picture quality, effectively preventing white strip watermarks or black strip watermarks and improving the picture quality. In addition, the invention improves the process degree of freedom.

Description

technical field [0001] The invention relates to a thin film transistor liquid crystal display structure and a manufacturing method thereof, in particular to a TFT-LCD array substrate and a manufacturing method thereof. Background technique [0002] In recent years, with the popularization of digital TV, the traditional CRT display has been gradually replaced by a new generation of display technology due to the difficulty of digitization, large size, heavy weight, and radiation. Representative new generation display technologies include PDP, OLED, LCD and so on. Among them, Thin Film Transistor Liquid Crystal Display (TFT-LCD) has the advantages of light weight, small size, low power consumption, no radiation, and high display resolution, and has gradually become a mainstream product. [0003] The main structure of TFT-LCD includes an array substrate and a color filter substrate in the box. On the array substrate, gate lines, data lines, and thin-film transistors and pixel e...
