图1为现有显示面板显示区域内的结构示意图；
图2为现有公共电极线的结构示意图；
图3为本发明显示面板显示区域内的结构示意图；
图4为本发明公共电极线的结构示意图。
 本发明的实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。在图中，结构相似的单元是以相同标号表示。
请参照图3和4，图3为本发明显示面板显示区域内的结构示意图。
如图3和4所示，本发明的显示面板可以为液晶显示面板，其包括：多条数据线11、多条扫描线12、像素电极（图中未出）以及公共电极21。
其中所述扫描线12位于第一金属层，所述扫描线12是通过对第一金属层进行图案化处理得到的。所述数据线11位于第二金属层，所述数据线12是通过对第二金属层进行图案化处理得到的。
所述公共电极21包括两个主干部211和多个分支部212。两个主干部211相对置，所述主干部211与所述分支部212位于不同层，所述分支部212的位置与所述数据线11的位置对应，其中两个所述主干部211均与所述分支部212电性连接。其中两个所述主干部211分别位于显示面板的上边缘和下边缘。两个主干部211之间平行设置。
其中多个所述分支部212之间相互平行，且多个分支部212位于两个所述主干部211所限定的区域内。也即分支部212位于所述主干部211的内侧。
其中所述主干部211沿第一方向排布，所述分支部212沿第二方向排布，所述第一方向与所述第二方向相垂直。比如所述主干部211沿水平方向排，所述分支部212沿竖直方向排布。
两个所述主干部211均通过过孔23与所述分支部212电性连接。例如，该分支部的材料比如为ITO，在涂布分支部的ITO层时，一并在过孔23内填充有ITO，使得主干部211与分支部212电性连接。
在一实施方式中，所述过孔23的位置与所述分支部212的端部的位置对应，使得分支部212的两个端部与主干部211电性连接。
为了减少制孔的工序，所述过孔23的位置与静电保护孔的位置对应，所述静电保护孔用于对所述数据线进行静电保护，比如将数据线上的静电通过静电保护孔释放掉。所述静电保护孔的位置与所述数据线的端部的位置对应。可以理解的，此时在该过孔内与数据线所在金属层对应的部分还设置有绝缘层，以防止分支部与数据线电性连接。
所述分支部212用于对所述显示面板中的异常点进行修复，此时所述分支部212与对应子像素的像素电极之间电性连接。比如，当显示面板出现异常点时，分别切断对应子像素的薄膜晶体管的源极和漏极，将该子像素的像素电极与分支部连接，使得该子像素的亮度变暗，由于人眼对暗点的明感度较低，从而提高了显示效果。
在一实施例中，为了简化制程工艺，降低生产成本，所述主干部211与所述扫描线12位于同一层，所述分支部212与所述像素电极位于同一层。也即所述主干部211与所述扫描线12均是通过对第一金属层进行图案化处理得到的，所述分支部212与所述像素电极均是通过对透明导电层进行图案化处理得到的。此时所述分支部212与像素电极之间间隔设置，也即两者彼此绝缘。
在另一实施例中，为了简化制程工艺，降低生产成本，所述主干部211与所述数据线11位于同一层，所述分支部212与所述像素电极位于同一层。也即所述主干部211与所述数据线11是对第二金属层进行图案化处理得到的，所述分支部212与所述像素电极是对透明导电层进行图案化处理得到的。此时所述分支部212与像素电极之间间隔设置，也即两者彼此绝缘。当然，可以理解的，分支部的设置方式不限于以上方式，比如为了降低开口率，还可以设置第三金属层，通过对第三金属层进行图案化处理，得到分支部。也即此时分支部与数据线、扫描线以及像素电极均不同层。
其中所述主干部211的材料为金属材料，所述分支部212的材料为氧化铟锡。
本发明还提供一种显示装置，其包括显示面板，如图3和4所示，本发明的显示面板包括：多条数据线11、多条扫描线12、像素电极（图中未出）以及公共电极21。
其中所述扫描线12位于第一金属层，所述扫描线12是通过对第一金属层进行图案化处理得到的。所述数据线11位于第二金属层，所述数据线12是通过对第二金属层进行图案化处理得到的。
所述公共电极21包括两个主干部211和多个分支部212；两个主干部211相对置，所述主干部211与所述分支部212位于不同层，所述分支部212的位置与所述数据线11的位置对应，其中两个所述主干部211均与所述分支部212电性连接。其中两个所述主干部211分别位于显示面板的上边缘和下边缘。两个主干部211之间平行设置。
其中多个所述分支部212之间相互平行，且多个分支部212位于两个所述主干部211所限定的区域内。也即分支部212位于所述主干部211的内侧。
其中所述主干部211沿第一方向排布，所述分支部212沿第二方向排布，所述第一方向与所述第二方向相垂直。比如所述主干部211沿水平方向排，所述分支部212沿竖直方向排布。
两个所述主干部211均通过过孔23与所述分支部212电性连接。例如，该分支部的材料比如为ITO，在涂布分支部的ITO层时，一并在过孔23内填充有ITO，使得主干部211与分支部212电性连接。
在一实施方式中，所述过孔23的位置与所述分支部212的端部的位置对应，使得分支部212的两个端部与主干部211电性连接。
为了减少制孔的工序，所述过孔23的位置与静电保护孔的位置对应，所述静电保护孔用于对所述数据线进行静电保护，比如将数据线上的静电通过静电保护孔释放掉。所述静电保护孔的位置与所述数据线的端部的位置对应。可以理解的，此时在该过孔内与数据线所在金属层对应的部分还设置有绝缘层，以防止分支部与数据线电性连接。
所述分支部212用于对所述显示面板中的异常点进行修复，此时所述分支部212与对应子像素的像素电极之间电性连接。比如，当显示面板出现异常点时，分别切断对应子像素的薄膜晶体管的源极和漏极，将该子像素的像素电极与分支部连接，使得该子像素的亮度变暗，由于人眼对暗点的明感度较低，从而提高了显示效果。
在一实施例中，为了简化制程工艺，降低生产成本，所述主干部211与所述扫描线12位于同一层，所述分支部212与所述像素电极位于同一层。也即所述主干部211与所述扫描线12均是通过对第一金属层进行图案化处理得到的，所述分支部212与所述像素电极均是通过对透明导电层进行图案化处理得到的。此时所述分支部212与像素电极之间间隔设置，也即两者彼此绝缘。
在另一实施例中，为了简化制程工艺，降低生产成本，所述主干部211与所述数据线11位于同一层，所述分支部212与所述像素电极位于同一层。也即所述主干部211与所述数据线11是对第二金属层进行图案化处理得到的，所述分支部212与所述像素电极是对透明导电层进行图案化处理得到的。此时所述分支部212与像素电极之间间隔设置，也即两者彼此绝缘。当然，可以理解的，分支部的设置方式不限于以上方式，比如为了降低开口率，还可以设置第三金属层，通过对第三金属层进行图案化处理，得到分支部。
其中所述主干部211的材料为金属材料，所述分支部212的材料为氧化铟锡。
本发明的显示面板及显示装置，通过将主干部与分支部设置在不同的层，且将分支部的位置与数据线的位置对应，从而避免分支部遮挡显示区域的光线，提高了开口率。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
