Description

液晶显示面板及液晶显示器 技术领域
本发明涉及一种液晶显示器制造技术领域， 尤其涉及一种液晶显示面板及 液晶显示器。 背景技术
液晶显示装置 （LCD, Liquid Crystal Display)具有机身薄、 省电、 无福射等 众多优点， 得到了广泛的应用。现有市场上的液晶显示装置大部分为背光型液 晶显示装置， 其包括液晶显示面板及背光模组（backlight module：)。液晶显示面 板的工作原理是在两片平行的玻璃基板当中放置液晶分子，通过玻璃基板通电 电压来控制液晶分子改变方向， 将背光模组的光线折射出来产生画面。 液晶分子的配向控制技术是制造液晶显示器 （liquid crystal display)最重要 的基本技术之一。 液晶显示器所显示的画面质量与液晶配向的优劣有关， 只有 使面板内的液晶材料呈稳定且均匀的排列， 才能呈现高质量的画面。一般用来 使液晶分子定向排列的薄层， 称为液晶配向层 （alignment layers：)。 目前， 由聚 合物稳定配向 (polymer— stabilized alignment, PSA)制程所制造而成的聚合物稳 定垂直配向型 (Polymer Stabilized Vertical Alignment, PSVA)液晶显示器，其可具 有广视角、 高开口率、 高对比及制程简单等优点， 因此得到广泛应用。
在 PSVA液晶显示器中， 两透明基板之间的液晶可被掺有反应型单体 (reactive monomer) , 其混合于液晶分子， 其中， 每一透明基板的表面涂布有聚 酰亚胺 (polyimide, PI), 其作为配向基材。 接着， 当施加电压及紫外光 (UV)光 照射于两透明基板时， 反应型单体可与液晶分子发生相分离 (phase separation) 现象， 而在透明基板的配向基材上形成聚合物。 由于聚合物跟液晶分子之间的 相互作用， 液晶分子会沿着聚合分子的方向来排列， 因此， 透明基板之间的液 晶分子可具有预倾角 pre-tile angle；)。 参阅图 1， 传统的液晶显示面板包括对置的上基板 210和下基板 220以及 设于所述上基板 210和下基板 220之间的液晶层 250。 其中， 上基板 210为薄 膜晶体管 （thin film transistor, TFT) 矩阵基板， 下基板 220上设有彩色滤光 (Color Filter, CF)层 240和黑色矩阵 230。使用 PSVA的配向制程中， UV光 从上基板 210的一侧照射， 这样可以防止彩色滤光层 240和黑色矩阵 230对 UV光的吸收， 从而使反应型单体 252与液晶分子 251发生相分离， 而在上基 板 210和下基板 220的配向基材上形成聚合物。 然而， 此种液晶显示面板的分 辨率 （resolution)较差、 像素 （pixel)的开口率较低， 且彩色滤光层 240与薄膜 晶体管矩阵基板接合时容易有对位误差 （misalignments 近年来， 提出了将彩色滤光层直接整合于薄膜晶体管矩阵基板上 (Color Filter on Array, COA)的技术， 由于彩色滤光层是仅直接形成于薄膜晶体管阵列 基板上， 因此不会产生对位误差。 而且， 此种液晶显示面板可具有较佳的分辨 率且其像素的开口率亦较高。 参阅图 2， 现有技术中的 COA液晶显示面板包 括对置的第一基板 110和第二基板 120以及设于第一基板 110和第二基板 120 之间的液晶层 150， 其中， 第一基板 110包括设有黑色矩阵 130的显示区 111 和围绕所述显示区 111的外围区 112， 第二基板 120为薄膜晶体管矩阵基板， 第二基板 120上设有包括红色滤光单元 141、 绿色滤光单元 142和蓝色滤光单 元 143的彩色滤光层 140。 使用 PSVA的配向制程中， UV光从第一基板 110 的一侧照射。 然而， 由于第一基板 110外围区 112上黑色矩阵 130会吸收 UV 光， 从而导致液晶层 150中会有反应型单体 152的残留， 在长时间驱动后， 带 电荷的反应型单体 152会产生带电离子， 而后这些带电荷的反应型单体 152和 带电离子的分布状况会逐渐产生变化，进而造成液晶显示面板的显示质量的劣 化。具体而言，在长时间驱动过程中，液晶层 150内的带电荷的反应型单体 152 和带电离子会依据其极性而产生分离的现象， 而这些依照极性分离后的带电荷 的反应型单体 152和带电离子会消耗一部份施加于液晶层的偏压， 使得作用于 液晶层上的偏压产生变异， 此现象称为屏蔽效应 （Screen effect)。 除此之外， 这些依照极性分离后的带电荷的反应型单体 152和带电离子会于液晶显示面板 中产生一寄生电位（Parasiticpotential),进而导致共享电压的飘移（V— com shift) 0 发明内容
在下面的描述中将部分地阐明本发明另外的方面和 /或优点， 通过描述，其 会变得更加清楚， 或者通过实施本发明可以了解。 为解决上述现有技术所存在的问题， 本发明的目的在于提供一种液晶显示 面板， 该面板可以防止在 PSVA制程中反应型单体的残留， 从而提高液晶显示 为了实现上述目的， 本发明提供的一种液晶显示面板， 包括对置的第一基 板和第二基板以及设于所述第一基板和第二基板之间的液晶层， 所述第一基板 包括设有黑色矩阵的显示区和围绕所述显示区的外围区， 所述外围区的黑色矩 阵上设有开口。
其中， 所述第二基板对应于所述开口处设有遮光单元。 其中， 所述遮光单元为色阻叠层。 其中， 所述色阻叠层为堆叠的红 /蓝色阻或者红 /绿色阻或者蓝 /绿色阻或者 红 /蓝 /绿色阻。 其中， 所述遮光单元与所述第一基板的带有开口的黑色矩阵区域有重叠。 其中，所述开口设于所述第一基板上对应于所述第二基板未设有跨线透明 电极的区域。 本发明的另一目的是提供一种包括上述液晶显示面板的液晶显示器。 其中， 所述第二基板对应于所述开口处设有遮光单元。 其中， 所述遮光单元为色阻叠层。 其中， 所述色阻叠层为堆叠的红 /蓝色阻或者红 /绿色阻或者蓝 /绿色阻或者 红 /蓝 /绿色阻。 其中， 所述遮光单元与所述第一基板的带有开口的黑色矩阵区域有重叠。 其中，所述开口设于所述第一基板上对应于所述第二基板未设有跨线透明 电极的区域。 本发明提供的液晶显示面板及液晶显示器，通过在第一基板的周边区的黑 色矩阵上设开口， 减小黑色矩阵对 UV光的吸收， 从而减小液晶层内反应型单 体的残留， 提高液晶显示面板的显示品质。 同时， 通过在第二基板对应于黑色 矩阵开口处设有的遮光单元， 防止出现开口处出现漏光现象。 附图说明

现在对本发明实施例进行详细的描述， 其示例表示在附图中， 其中， 相同 的标号始终表示相同部件。 下面通过参照附图对实施例进行描述以解释本发 明。
参阅图 3和图 4， 为本实施例提供的液晶显示面板的俯视图以及 PSVA配 向制程时 UV光照射示意图。 本实施例提供的液晶面包括对置的第一基板 110 和第二基板 120以及设于第一基板 110和第二基板 120之间的液晶层 150， 其 中， 第一基板 110包括设有黑色矩阵的显示区 111和围绕显示区 111的外围区 112； 第二基板 120为薄膜晶体管矩阵基板； 第二基板 120对应于显示区处设 有彩色滤光层 140， 彩色滤光层包括红色滤光单元 141、 绿色滤光单元 142和 蓝色滤光单元 143。 为了减小 PSVA制程时黑色矩阵对紫外光的吸收， 在第一 基板 110的外围区 112的黑色矩阵 130上设有开口 131。 使用 PSVA的配向制程中， 紫外光从第一基板 110的一侧照射。 由于在第 一基板 110的周边区的黑色矩阵 130上的设有开口 131， 紫外光可以直接照射 到液晶层 150而不被黑色矩阵 130吸收，从而使反应型单体 152与液晶分子 151 分离并在第一基板 110和第二基板 120的配向基材上形成聚合物， 从而减少液 晶层 150内的反应型单体 152的残留， 进而提高液晶显示面板的显示品质。 进一歩地， 在第二基板对应于所述开口 131处设有遮光单元 160， 所述遮 光单元 160为包括叠放的红色阻、 绿色阻和蓝色阻中的至少两个的色阻叠层， 其叠放次序不固定。 在本实施例中， 遮光单元 160包括一次叠放的红色阻 161 和蓝色阻 162。 当然， 在其他实施例中， 遮光单元 160也可以为如黑色矩阵的 吸光层或者是反光层。 这样可以防止该液晶显示面板在使用时出现从外围区
112的开口 131处漏光的现象。 进一歩地， 遮光单元 160与第一基板 120的带 有开口 131的黑色矩阵 130区域有重叠， 这样可以进一歩改善外围区 112的开 口 131处的漏光现象。
进一歩地，在第一基板 110的外围区 112的黑色矩阵 130上设有的开口 131 位于第一基板 110上对应于所述第二基板 120的未设有跨线透明电极的区域， 这样可以避免遮光单元 160对工艺的影响。 基于同一发明构想， 本发明实施例提供了一种液晶显示器， 包括上述液晶 显示面板。
综上所述， 本发明提供的液晶显示面板及液晶显示器， 通过在第一基板的 周边区的黑色矩阵上设开口， 减小黑色矩阵对 UV光的吸收， 从而减小液晶层 内反应型单体的残留， 提高液晶显示面板的显示品质。 同时， 通过在第二基板 对应于黑色矩阵开口处设有的遮光单元， 防止出现开口处出现漏光现象。 需要说明的是， 在本文中， 诸如第一和第二等之类的关系术语仅仅用来将 一个实体或者操作与另一个实体或操作区分开来， 而不一定要求或者暗示这些 实体或操作之间存在任何这种实际的关系或者顺序。 而且， 术语"包括"、 "包 含"或者其任何其他变体意在涵盖非排他性的包含， 从而使得包括一系列要素 的过程、 方法、 物品或者设备不仅包括那些要素， 而且还包括没有明确列出的 其他要素， 或者是还包括为这种过程、 方法、 物品或者设备所固有的要素。在 没有更多限制的情况下， 由语句 "包括一个 ...... "限定的要素， 并不排除在包括 所述要素的过程、 方法、 物品或者设备中还存在另外的相同要素。 虽然本发明是参照其示例性的实施例被具体描述和显示的， 但是本领域的 普通技术人员应该理解， 在不脱离由权利要求限定的本发明的精神和范围的情 况下， 可以对其进行形式和细节的各种改变。
