相较于现有的像素结构及液晶显示面板，本发明的像素结构及液晶显示面板设置结构不同的第一子电极和第二子电极，在保持现有的液晶显示装置的制作成本的基础上，增大了液晶显示装置的观看视角；解决了现有的像素结构及液晶显示面板的制作成本较高或观看视角较小的技术问题。

 本发明的最佳实施方式
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2A和图2B，图2A为本发明的液晶显示面板的像素结构的像素电极的结构示意图；图2B为沿图2A的B-B’截面线的截面图。本优选实施例的像素结构20包括基板23、绝缘层22以及像素电极21，像素结构20的其他部分，如用于制作薄膜晶体管的金属层以及绝缘层等已省略，像素结构20的其他部分的结构与现有技术中的像素结构的相应部分的结构相同。
其中绝缘层22设置在基板23上，像素电极21设置在绝缘层22上，并通过薄膜晶体管24与液晶显示面板的相应的数据线25和扫描线26连接。在本优选实施例中，像素电极21包括第一子电极211以及第二子电极212，第一子电极211间隔的设置在绝缘层22的第一区域C上，第二子电极212连续的设置在绝缘层22的第二区域D上。第一区域C为绝缘层22的平坦区域，第二区域D为绝缘层22的凹槽区域，即第一区域C的绝缘层22均位于一个水平面内，第二区域D的绝缘层22位于至少两个水平面内，即第二区域D的绝缘层22包括凹槽221以及凸起222。
第二子电极212包括设置在绝缘层22的凹槽221中的凹槽子电极2121以及设置在绝缘层22的凸起222上的凸起子电极2122，同一显示畴中凹槽子电极2121和凸起子电极2122相互连接。第二区域D的绝缘层22中的凹槽221以及凸起222呈条状分布，因此设置在凹槽221中的凹槽子电极2121和设置在凸起222上的凸起子电极2122也呈条状分布，间隔设置在第一区域C的绝缘层22上的第一子电极211也呈条状分布。凹槽子电极2121的延伸方向、凸起子电极2122的延伸方向以及第一子电极211的延伸方向相互平行。
如图2A所示，本优选实施例的像素结构20具有第一显示畴31、第二显示畴32、第三显示畴33以及第四显示畴34。第一显示畴31的第一子电极211和第二显示畴32的第一子电极211关于像素电极21的第一中心线213对称，第一显示畴31的第二子电极212和第二显示畴21的第二子电极212关于像素电极21的第一中心线213对称，第三显示畴33的第一子电极211和第四显示畴34的第一子电极211关于像素电极的第一中心线213对称，第三显示畴33的第二子电极212和第四显示畴34的第二子电极212关于像素电极21的第一中心线213对称，其中第一中心线213与液晶显示面板的数据线25平行。
第一显示畴31的第一子电极211和第三显示畴33的第一子电极211关于像素电极21的第二中心线214对称，第一显示畴31的第二子电极212和第三显示畴33的第二子电极212关于像素电极21的第二中心线214对称，第二显示畴32的第一子电极211和第四显示畴24的第一子电极211关于像素电极21的第二中心线214对称，第二显示畴32的第二子电极212和第四显示畴34的第二子电极212关于像素电极21的第二中心线214对称，其中第二中心线214与液晶显示面板的扫描线26平行。
当向本优选实施例的像素结构20的像素电极21施加相同电压时，每个显示畴对应的液晶分子均具有相同的倾倒方向，但是由于每个显示畴的第一子电极211和第二子电极212所形成的电场有所差异，使得同一显示畴的第一子电极211对应的液晶分子和第二子电极212对应的液晶分子的倾倒角度不同，从而在同一显示畴中实现了两个子显示畴，这样图2A中的像素结构具有八个不同的子显示畴，从而可以有效的改善液晶显示面板的观看视角，同时第一子电极211和第二子电极212可以同时形成，并不会增加液晶显示面板的制作成本，因此在保证现有的液晶显示面板的制作成本的基础上，增大了液晶显示面板的观看角度。
本优选实施例的像素结构设置结构不同的第一子电极和第二子电极，在保持现有的液晶显示装置的制作成本的基础上，增大了液晶显示装置的观看视角。
本发明还提供一种液晶显示面板，该液晶显示面板包括数据线、扫描线以及像素结构，数据线用于传输数据信号，扫描线用于传输扫描信号，像素结构由数据线和扫描线交错而成，该像素结构包括基板、绝缘层以及像素电极。其中绝缘层设置在基板上，像素电极设置在绝缘层上，并与液晶显示面板的相应的数据线和扫描线连接。
像素电极包括第一子电极以及第二子电极，第一子电极间隔的设置在绝缘层的第一区域上，第二子电极连续的设置在绝缘层的第二区域上。第一区域为绝缘层的平坦区域，第二区域为绝缘层的凹槽区域。
优选的，第二子电极包括设置在绝缘层的凹槽中的凹槽子电极以及设置在绝缘层的凸起上的凸起子电极，凹槽子电极和凸起子电极相互连接。
优选的，凹槽子电极的延伸方向、凸起子电极的延伸方向以及第一子电极的延伸方向相互平行。
优选的，像素结构具有第一显示畴、第二显示畴、第三显示畴以及第四显示畴。第一显示畴的第一子电极和第二显示畴的第一子电极关于像素电极的第一中心线对称，第一显示畴的第二子电极和第二显示畴的第二子电极关于像素电极的第一中心线对称，第三显示畴的第一子电极和第四显示畴的第一子电极关于像素电极的第一中心线对称，第三显示畴的第二子电极和第四显示畴的第二子电极关于像素电极的第一中心线对称，其中第一中心线与液晶显示面板的数据线平行。
优选的，第一显示畴的第一子电极和第三显示畴的第一子电极关于像素电极的第二中心线对称，第一显示畴的第二子电极和第三显示畴的第二子电极关于像素电极的第二中心线对称，第二显示畴的第一子电极和第四显示畴的第一子电极关于像素电极的第二中心线对称，第二显示畴的第二子电极和第四显示畴的第二子电极关于像素电极的第二中心线对称，其中第二中心线与液晶显示面板的扫描线平行。

本发明的像素结构及液晶显示面板设置结构不同的第一子电极和第二子电极，在保持现有的液晶显示装置的制作成本的基础上，增大了液晶显示装置的观看视角；解决了现有的像素结构及液晶显示面板的制作成本较高或观看视角较小的技术问题。
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。
