Abstract

The invention relates to a TFT-LCD pixel structure, a manufacturing method and a broken wire repairing method. The TFT-LCD pixel structure comprises a plurality of pixel cells limited by a grid wire and a data wire, wherein a thin-film transistor and a pixel electrode are formed in each pixel cell, a first public electrode wire is formed on the lower side of the grid wire, a second public electrode wire is formed on the upper side of the grid wire, a first light blocking strip is formed on the left side of the pixel cell, and a second light blocking strip is formed on the right side of the pixel cell; the first public electrode wire, the second public electrode wire, the first light blocking strip and the second light blocking strip form an integrated structure and form an annular structure on the periphery of the pixel cell; and the second public electrode wire positioned on the upper side of the grid wire is connected with the first public electrode positioned on the lower side of the grid wire through a connecting electrode. The TFT-LCD pixel structure can be repaired quickly and efficiently, and has high success rate.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a TFT-LCD pixel structure, a manufacturing method and a disconnection repairing method. Background technique [0002] Liquid Crystal Display (LCD) has the characteristics of small size, low power consumption, and no radiation, and has now occupied a dominant position in the field of flat panel display. The main structure of the liquid crystal display includes an array substrate and a color filter substrate that are boxed together and the liquid crystal is sandwiched between them. On the array substrate, gate lines that provide scanning signals, data lines that provide data signals, and pixel electrodes that form pixel points are formed. The manufacturing process of liquid crystal displays mainly includes the array process of preparing the array substrate and the color film substrate, the box forming process of combining the array substrate and the color film substrate and dripping the ...
