Abstract
A display panel is provided. In a plan view of the display panel, the black matrix layer covers the first connection portion and the second connection portion, and the second common electrode and the pixel portion are in an area of the opening, where an angle formed between an extension direction of the first connection portion and an extension direction of the first branch electrode is greater than or equal to 120 degrees and less than 180 degrees, or the extension direction of the first connection portion coincides with the extension direction of the first branch electrode.
Claims19
A display panel, comprising:
- an array substrate, a liquid crystal layer, and an opposite substrate disposed sequentially;
- wherein
- the opposite substrate comprises a first substrate, a black matrix layer, and a first common electrode, wherein the black matrix layer is disposed at a side of the first substrate close to the liquid crystal layer, the first common electrode is disposed at a side of the black matrix layer close to the liquid crystal layer, and the black matrix layer is provided with an opening;
- the array substrate comprises a second substrate and a pixel electrode, wherein the pixel electrode is disposed at a side of the second substrate close to the liquid crystal layer;
