Description

一种液晶显示面板及液晶显示器 技术领域
本发明涉及液晶显示领域，特别是涉及一种液晶显示面板及液晶显示器。
 背景技术
随着大尺寸液晶显示面板的推出，液晶显示面板必须具备广视角特性方能满足使用上的需求。因此，具有广视角特性的多区域垂直配向(multi-domainvertical alignment，MVA)液晶显示面板已成为目前大尺寸平面显示面板的主流产品
垂直配向液晶显示面板的阵列基板(array substrate)具有图案化的像素电极，而彩色滤光片基板(color filter substrate，CF基板)通常包含有多个凸块，对应设置在像素电极的中心位置。通过像素电极的边缘电场效应(fringe electric field effect)与凸块的几何形状诱导液晶分子的倒向，使得负型液晶分子在像素施加电压时倒下，并且根据液晶分子倾倒方向的不同而形成不同显示区域(domain)，以获得广视角的特性。
对于常规COA产品（Color On Array），像素电极P通过连接体（例如像素电极延伸部P1）穿过通孔H与漏极电极D相连接。结构上色阻层介于漏极电极层与像素电极层之间，为保证漏极电极与像素电极导通，需要对通孔附近的色阻挖掉，形成一个彩膜孔洞K区域，而色阻膜层很厚，所以彩膜孔洞区域的地形犹如一个大洞，液晶分子会堆积在这里。由于该像素电极P的延伸部P1为比较窄比较细的形状，充电后，其与上板间形成的电场方向是发散的。由于“像素电极的延伸部P1”与彩膜孔洞K区域的共同影响，拍打面板时彩膜孔洞区域的液晶分子更容易发生倾倒（见图1a、图1b及1c），并与相邻位置的液晶分子互相影响，形成暗纹，且暗纹的形状一般由彩膜孔洞区域到像素电极中心，容易在显示画面时导致残影现象(image retention，IR)，因而影响画质。
因此，现有技术存在缺陷，急需改进。

本实施例中，色阻层4在像素电极2与薄膜晶体管3的漏极连接所在区域设置通孔41，在该通孔41边缘设置可将该通孔41所在区域的液晶分子与显示区域的液晶分子间隔开的间隔件结构9，可将通孔41所在区域的液晶分子与像素电极2所在区域的液晶分子间隔开，使得通孔41所在区域的液晶分子与像素电极所在区域的液晶分子不会互相影响，减少残像或暗纹等现象，提高显示品质。
本发明还提供一种液晶显示器，该液晶显示器包括背光结构及液晶显示面板，该背光结构可采用现有的背光结构，该液晶显示面板的具体结构与上述实施例的液晶显示面板结构基本一致，具体的结构描述及所带来的技术效果可参考上述实施例的描述，此处不再赘述。
本发明中，在色阻层4正对像素电极2与薄膜晶体管3的漏极连接所在区域设置通孔41，对应通孔41所在区域边缘设置间隔件9，可将通孔41所在区域的液晶分子与像素电极2所在区域的液晶分子间隔开，使得通孔41所在区域的液晶分子与像素电极2所在区域的液晶分子不会互相影响，减少残像或暗纹等现象，提高显示品质。
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。
