Problems solved by technology

However, since the fineness of the black matrix is ​​lower than that of the storage electrode lines 13, and there will be an alignment error between the thin film transistor substrate and the color filter substrate during assembly, it will cause the gate line 11 to be distorted. Areas on the other side create light leakage issues

Abstract

The invention discloses a film transistor substrate of a liquid crystal display panel, comprising a substrate, multiple grid lines, multiple data lines, multiple storage electrode lines, multiple shielding leads and multiple pixel electrodes. The data line and the grid line defines a plurality of pixel areas in an array on the substrate. Each storage electrode line penetrates a corresponding pixel area and divides the pixel area into a first area and a second area. The shielding leads are respectively disposed in the pixel area and each shielding lead comprises a first shielding lead section in the first area and a second shielding lead section in the second area. The pixel electrodes are respectively disposed in each pixel area, and are respectively in an electrical connection with the corresponding first shielding lead section and the second shielding lead section.

Description

technical field [0001] The present invention relates to a thin film transistor substrate of a liquid crystal display panel, especially a liquid crystal with a storage electrode line penetrating the pixel area and shielding wires located on both sides of the storage electrode line and electrically connected to the pixel electrode in the pixel area. Thin-film transistor substrates for display panels. Background technique [0002] Please refer to figure 1 , figure 1 A schematic diagram of a thin film transistor substrate of a conventional liquid crystal display panel is shown. Such as figure 1 As shown, the TFT substrate 1 of the conventional liquid crystal display panel includes a substrate 10 , a plurality of gate lines 11 , a plurality of data lines 12 and a plurality of storage electrode lines 13 . Each gate line 11 extends along a first direction S1 (such as a horizontal direction), and the gate lines 11 are arranged parallel to each other on the substrate 10, and each...
