    Abstract: An array substrate and a liquid crystal display are disclosed. Each of the pixel cells includes a first, a second and a third pixel electrode, and a first, a second, a third, and a fourth switch. One corresponding scanning line are configured to turn on or off the four switches. The corresponding first data line inputs the first data signals to the first pixel electrode via the first switch. The corresponding second data line inputs the second data signals to the second pixel electrode and the third pixel electrode by the second switch and the third switch. The first end of the fourth switch connects to one of the second pixel electrode and the third pixel electrode. The second end of the fourth switch connects to the common electrode. In this way, the array substrate not only increases the aperture rate in the 2D display mode, but also decreases the cross talk effect in the 3D display mode. In addition, the number of the scanning drivers is reduced.

    Abstract: An electrode structure and a liquid crystal display panel are disclosed. The electrode structure comprises a first trunk electrode and a second trunk electrode, the first trunk electrode and the second trunk electrode intersecting with each other to form a trunk electrode intersecting point; and a plurality of branch electrodes, the branch electrodes being spaced from one another, and one end of each branch electrode being connected with at least one of the first trunk electrode and the second trunk electrode and forming a trunk-branch angle with a corresponding trunk electrode. The trunk-branch angles of the branch electrodes decrease gradually or increase gradually along a direction from the trunk electrode intersecting point to far therefrom. An electric field distribution in the electrode structure can be optimized, and an orientation of liquid crystal can be optimized accordingly. Therefore, a display performance of the liquid crystal display panel under a wide viewing angle can be improved, and an aperture ratio thereof can be maintained.
