Description

液晶显示面板 技术领域
本发明属于液晶显示技术领域，具体地讲，涉及一种多畴垂直(MVA)取向型液晶显示面板。
背景技术
随着光电与半导体技术的演进，也带动了平板显示器(Flat Panel Display)的蓬勃发展，而在诸多平板显示器中，液晶显示器(Liquid Crystal Display，简称LCD)因具有高空间利用效率、低消耗功率、无辐射以及低电磁干扰等诸多优越特性，已成为市场的主流。
在液晶显示器的各种显示模式中，垂直排列(Vertical Alignment，VA)显示模式由于其良好的视角特性受到市场的欢迎。在VA显示模式的LCD中，像素单元内液晶分子的长轴在不加电的状态下与滤光片垂直，每个像素单元被划分为多个畴区(多畴)，在加电状态下，每个畴区内的液晶分子向各自的方向偏转，通过这种方法，将同一像素单元中的液晶分子取向分为多个方向，由此补偿各个角度的视角，进而实现各个视角方向的均匀显示，以有效改善不同观察角度的灰阶显示状态下的视角特性。
现有技术中，实现像素单元中的多个畴区可以由以下方式实现：由像素电极的裂缝形成侧向电场的PVA(Patterned VA)模式；由像素单元中的凸起(Protrusions)结构来使液晶分子形成多畴排列的MVA(Multi-domain VA)模式。但是在现有的液晶显示面板中，为了保持液晶显示面板之间的间隔，会在不同区域设置两种隔离子，其中一种为主隔离子，另一种为副隔离子，二者均位于黑色矩阵上，如果将上述凸起结构也设置在像素单元中，会使结构复杂，增加制作难度，且会增加生产成本。

具体实施方式
以下，将参照附图来详细描述本发明的实施例。然而，可以以许多不同的形式来实施本发明，并且本发明不应该被解释为限制于这里阐述的具体实施例。相反，提供这些实施例是为了解释本发明的原理及其实际应用，从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的各种修改。
在附图中，相同的标号将始终被用于表示相同的元件。将理解的是，尽管在这里可使用术语“第一”、“第二”等来描述各种元件，但是这些元件不应受这些术语的限制。这些术语仅用于将一个元件与另一个元件区分开来。
图1是根据本发明的第一实施例的多畴垂直显示模式液晶显示面板的结构示意图。图2是根据本发明的第一实施例的第一基板的正视图。其中，在图2中，黑色矩阵112、彩色滤光层113和公共电极层114被覆盖在绝缘层115之下，并且图2中未示出第一配向膜层118。
参照图1和图2，根据本发明的第一实施例的多畴垂直(Multi-domain Vertical Alignment，MVA)显示模式液晶显示面板包括第一基板111、第二基板121及液晶层130，其中，第一基板111与第二基板121对盒设置，液晶层130设置在第一基板111与第二基板121之间。优选的，在根据本发明的第一实施例中，液晶层130中包含负性的液晶分子，但本发明并不限制于此。
第二基板121的显示区域包含有多个子像素区域SP，且第二基板121上设置有若干阵列排布的开关管(例如，薄膜晶体管)122，其中，每个开关管122的像素电极1221设置在其对应的子像素区域SP中。在第二基板121上还设置有第二配向膜层123，其中，该第二配向膜层123将所有开关管122及所有子像素区域SP完全覆盖其下。在根据本发明的第一实施例中，该第二配向膜层123可采用聚酰亚胺树脂(Polyimide Resin，PI)材料形成。
在第一基板111上设置有：黑色矩阵112、彩色滤光层113、公共电极层114、绝缘层115、若干主隔离子(Main Photo Spacer，MPS)116a、若干副隔离子(Sub Photo Spacer，SPS)116b、第一导电膜层117及第一配向膜层118。
黑色矩阵(BM)112形成在第一基板111上，其中，黑色矩阵112可由黑色树脂或者金属铬制成。在第二基板121上形成的开关管122与黑色矩阵112 正对。彩色滤光层113形成在第一基板111上，并覆盖黑色矩阵112，其中，该彩色滤光层113包括依次形成的红色(R)色阻层、绿色(G)色阻层和蓝色(B)色阻层。
公共电极层114形成在彩色滤光层113上，其中，公共电极层114可由透明的氧化铟锡(ITO)材料制成。绝缘层115形成在公共电极层114上，若干主隔离子116a及若干副隔离子116b设置在绝缘层115上，这样，绝缘层115可将公共电极层115与主隔离子116a、副隔离子116b进行隔离。
主隔离子116a间隔位于黑色矩阵112的下方，且主隔离子116a顶接第二基板结构，其中，主隔离子用于保持第一基板结构与第二基板结构之间的间隔。在本实施例中，每个子像素区域SP均对应一个副隔离子116b，而主隔离子116a的布置密度小于副隔离子116b的布置密度。
每个副隔离子116b位于其对应的子像素区域SP的上方且与第二配向膜层123具有一定的间隔，其中，每个副隔离子116b可由树脂等弹性材料形成，也可由二氧化硅等硬性材料形成。优选的，在根据本发明的第一实施例中，每个副隔离子116b位于其对应的子像素区域SP中心处的上方。优选的，在根据本发明的第一实施例中，每个副隔离子116b呈梯柱状。
第一导电膜层117设置于绝缘层115上且覆盖每个副隔离子116b，其中，第一导电膜层117可由透明的氧化铟锡(ITO)材料制成。第一配向膜层118覆盖除每个副隔离子116b上的第一导电膜层117之外的第一导电膜层117以及除第一导电膜层117覆盖的绝缘层115之外的绝缘层115，也就是说，第一导电膜层117只覆盖绝缘层115的部分。第一导电膜层117为密布的极细的电极图案(pattern)，以使液晶显示面板在正常显示时尽量减小第一导电膜层117对公共电极层114的屏蔽作用。
此外，第一配向膜层118不覆盖主隔离子116a。第一配向膜层118可采用聚酰亚胺树脂(Polyimide Resin，PI)材料形成。
在根据本发明的第一实施例中，先将第一导电膜层117与每个开关管122的像素电极1221进行通电导通，这时液晶层130中包含的负性液晶分子会围绕副隔离子116b形成具有一定预倾角(Pre-tiltAngle)的定向排列；然后采用 紫外光(UV)光照射，液晶层130中添加的紫外光固化单体进行聚合反应，从而固定液晶分子围绕副隔离子116b形成多畴排列，进行形成多畴垂直显示模式液晶显示面板。
图3是根据本发明的第二实施例的多畴垂直显示模式液晶显示面板的结构示意图。图4是根据本发明的第二实施例的第一基板的正视图。其中，在图4中，黑色矩阵112、彩色滤光层113和公共电极层114被覆盖在绝缘层115之下，并且图2中未示出第一配向膜层118。

第二基板121的显示区域包含有多个子像素区域SP，且第二基板121上设置有若干阵列排布的开关管(例如，薄膜晶体管)122，其中，每个开关管122的像素电极1221设置在其对应的子像素区域SP中。在第二基板121上还设置有第二配向膜层123，其中，该第二配向膜层123将所有开关管122及所有子像素区域SP完全覆盖其下。在根据本发明的第二实施例中，该第二配向膜层123可采用聚酰亚胺树脂(Polyimide Resin，PI)材料形成。
在第一基板111上设置有：黑色矩阵112、彩色滤光层113、公共电极层114、绝缘层115、若干主隔离子116a、若干导电副隔离子119、第一导电膜层117及第一配向膜层118。
黑色矩阵(BM)112形成在第一基板111上，其中，黑色矩阵112可由黑色树脂或者金属铬制成。在第二基板121上形成的开关管122与黑色矩阵112正对。彩色滤光层113形成在第一基板111上，并覆盖黑色矩阵112，其中，该彩色滤光层113包括依次形成的红色(R)色阻层、绿色(G)色阻层和蓝色(B)色阻层。
公共电极层114形成在彩色滤光层113上，其中，公共电极层114可由透明的氧化铟锡(ITO)材料制成。绝缘层115形成在公共电极层114上，若干 主隔离子116a及若干导电副隔离子119设置在绝缘层115上，这样，绝缘层115可将公共电极层115与主隔离子116a、导电副隔离子119进行隔离。
主隔离子116a间隔位于黑色矩阵112的下方，且主隔离子116a顶接第二基板结构，其中，主隔离子用于保持第一基板结构与第二基板结构之间的间隔。在本实施例中，每个子像素区域SP均对应一个导电副隔离子119，而主隔离子116a的布置密度小于导电副隔离子119的布置密度。
每个导电副隔离子119位于其对应的子像素区域SP的上方且与第二配向膜层123具有一定的间隔，其中，每个导电副隔离子119可由铝等金属材料形成。优选的，在根据本发明的第二实施例中，每个导电副隔离子119位于其对应的子像素区域SP中心处的上方。优选的，在根据本发明的第二实施例中，每个导电副隔离子119呈梯柱状。
第一导电膜层117设置于绝缘层115上，并且第一导电膜层117与每个导电副隔离子119的底部接触，其中，第一导电膜层117可由透明的氧化铟锡(ITO)材料制成。第一配向膜层118覆盖第一导电膜层117以及除第一导电膜层117覆盖的绝缘层115之外的绝缘层115，也就是说，第一导电膜层117只覆盖绝缘层115的部分。第一导电膜层117为密布的极细的电极图案(pattern)，以使液晶显示面板在正常显示时尽量减小第一导电膜层117对公共电极层114的屏蔽作用。
此外，第一配向膜层118不覆盖主隔离子116a。第一配向膜层118可采用聚酰亚胺树脂(Polyimide Resin，PI)材料形成。
在根据本发明的第二实施例中，先将第一导电膜层117与每个开关管122的像素电极1221进行通电导通，这里，由于第一导电膜层117与每个导电副隔离子119的底部接触，所以每个导电副隔离子119也被通电，这时液晶层130中包含的负性液晶分子会围绕导电副隔离子119形成具有一定预倾角(Pre-tilt Angle)的定向排列；然后采用紫外光(UV)光照射，液晶层130中添加的紫外光固化单体进行聚合反应，从而固定液晶分子围绕导电副隔离子119形成多畴排列，进行形成多畴垂直显示模式液晶显示面板。
综上所述，在根据本发明的实施例中，利用第一基板与第二基板之间的副 隔离子实现液晶分子更均匀的取向，与现有技术中的多畴垂直显示模式液晶显示面板相比，无需额外的使用凸起(Protrusions)结构实现液晶分子的取向，简化液晶显示面板的制造工序，且节省成本。
虽然已经参照特定实施例示出并描述了本发明，但是本领域的技术人员将理解：在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下，可在此进行形式和细节上的各种变化。
