- the fringe field is well superimposed, and the fringe field between the pixel electrode and the sub-signal line does not affect the fringe field between the pixel electrode and the common electrode, and preferably the dry electrode of the common electrode is on the double-gate array substrate.

- the cross-sectional view shown since the increase of the overlap region increases the electric field required for the rotation of the liquid crystal, it is more important that the increased overlap region is located at the boundary between the pixel electrode and the sub-signal line. Therefore, the liquid crystal at the junction can be caused to rotate, thereby increasing the transmittance of the panel.
- the branch electrode 512 is provided with a corner structure 55 at the boundary between adjacent pixel units Q. Since the signal lines are disposed between adjacent pixel units, the black matrix is required to be blocked, and thus display defects due to touch are apt to occur in the areas where the signal lines are located. Therefore, the present invention provides a corner structure at the boundary between adjacent pixel units, which can improve such display defects, thereby alleviating display unevenness caused by movement or pressing of the touch process.
- the material of the sub signal line is metal or transparent oxide.
- the sub signal line is made of indium tin oxide.
