Abstract

A liquid crystal display panel includes a first substrate, a second substrate, a liquid crystal layer and an electrode structure. The second substrate is parallel to the first substrate. The liquid crystal layer is located between the first substrate and the second substrate. The electrode structure is disposed on the first substrate. The electrode structure includes a first branch portion and a second branch portion. The first branch portion includes first branch electrodes. The two adjacent first branch electrodes are parallel to each other and separated apart by a first interval. The second branch portion includes second branch electrodes. The two adjacent second branch electrodes are parallel to each other and separated apart by a second interval. Any first branch electrode corresponds to at least part of one of the second intervals. Any second branch electrode corresponds to at least part of one of the first intervals.

Claims (18)

1. A liquid crystal display panel, comprising:

a first substrate;

a second substrate substantially parallel to the first substrate;

a liquid crystal layer located between the first substrate and the second substrate; and

an electrode structure disposed on the first substrate, wherein the electrode structure comprises:

a first branch portion comprising a plurality of first branch electrodes, wherein the two adjacent first branch electrodes are substantially parallel to each other and separated apart by a first interval;

a second branch portion comprising a plurality of second branch electrodes, wherein the two adjacent second branch electrodes are substantially parallel to each other and separated apart by a second interval, an end edge of each of the first branch electrodes exactly corresponds to one of the second intervals, and an end edge of each of the second branch electrodes exactly corresponds to one of the first intervals; and

a main electrode having a first inclined side and a second inclined side, wherein the first inclined side and the second inclined side form an indent, each first branch electrode is connected to the first inclined side to be located inside the indent, and each second branch electrode is connected to the second inclined side to be located inside the indent.

2. A liquid crystal display device, comprising:

a liquid crystal display panel, comprising:

a first substrate;
