Claim 0:
1. A liquid crystal display panel, comprising a first substrate and a second substrate disposed opposite to each other, wherein a liquid crystal layer is disposed between the first substrate and the second substrate and comprises a plurality of liquid crystal molecules, a common electrode is disposed on a side of the second substrate facing the first substrate, a plurality of scan lines and a plurality of data lines are disposed on the first substrate, and the scan lines and the data lines intersect to define a plurality of pixel units; and
a pixel electrode is disposed in each pixel unit, the pixel electrode comprises a trunk electrode and a plurality of branch electrodes, and the trunk electrode comprises a first trunk electrode and a second trunk electrode intersecting each other,
wherein a first metal line is disposed on the first substrate, an orthographic projection of the first metal line on a plane where the pixel electrode is located covers at least part of the first trunk electrode, and a voltage difference between the common electrode and the first metal line causes a liquid crystal molecule corresponding to the first metal line to be in an opaque state;
wherein the voltage difference between the common electrode and the first metal line is V1, and −1 V≤V1≤+1 V;
wherein a second metal line configured to shield light leaked at the scan lines is disposed on the first substrate, an orthographic projection of the second metal line on a plane where the scan lines are located falls on the scan lines, a voltage difference between the second metal line and the common electrode is V2, and V2=V1;
wherein a third metal line configured to shield light leaked at the data lines is disposed on the first substrate, an orthographic projection of the third metal line on a plane where the data lines are located covers the data lines, the third metal line is connected in series with the second metal line, a voltage difference between the third metal line and the common electrode is V3, and V3=V1;
wherein the first metal line, the second metal line, and the third metal line are disposed in the same layer.
