Description

一种液晶显示器及其制造方法
本申请要求于 2013 年 12 月 31 日提交中国专利局、 申请号为 201310747855.6、 发明名称为 "一种液晶显示器及其制造方法" 的中国专利 申请的优先权, 上述专利的全部内容通过引用结合在本申请中。 技术领域
本发明涉及薄膜晶体管液晶显示装置( Thin Film Transistor liquid crystal display, TFT-LCD ) 的制造领域, 特别涉及一种液晶显示器及其制造方法。 背景技术
如图 1所示,是现有的一种 PSVA模式(高分子安定化垂直配向, Polymer Stabilization Vertical-Alignment )的液晶显示器常用的像素电极的示意图; 在 图中示出了一个像素电极。 在现有的这种 PSVA模式的液晶显示器中, 其像 素电极被设计为 "米" 字型, 由中间的竖直主干 80, 水平主干 81和与 X轴 夹角为 ± 45度, ± 135度的分支 82三部分组成。 其中竖直主干 80和水平主 干 81将像素面积平均分成 4个区域, 每个区域都由斜向 45度的分支 82平 铺组成。
如图 2所示, 是对图 1的像素电极施加电压后的液晶倒向示意图; 图 2 是是采用对图 1的像素电极施加 4V的电压后,液晶分子 90由像素电极外侧 开始逐渐向内侧倾倒。 倾倒的角度是沿切口方向 (即沿分支 82的方向, 如 图中箭头方向所示), 4个区域的液晶倾倒方向分别为 ± 45度, ± 135度, 都 指向像素的中央区域。如上图所示液晶倒向与 X轴的夹角为:第一象限为 -135 度,第二象限为 -45度,第三象限为 45度,第四象限为 135度。现有的 PSVA 制程是通过将像素电极设计成 "米" 字形来控制液晶分子的配向来改善大视 角色偏的问题。

如图 3及图 4所示, 为本发明提供的一种液晶显示器的一个实施例的结 构示意图, 该液晶显示器包括:
TFT阵列基板 1 , 具有第一电极层 15与覆盖第一电极层 15的第一配向 层 19,在 TFT阵列基板的玻璃基板 11与钝化层 180之间形成彩膜层 18,还 设置有黑矩阵( Black Matrix ) 22;
CF ( Color Filter, 彩膜)基板 2, 具有第二电极层 24与覆盖第二电极层 24的第二配向层 29;
液晶层 3 ,配置于 TFT阵列基板 1的第一配向层 19与 CF基板 2的第二 配向层 29之间;
其中, 第一配向层 19与第二配向层 29均被划分为至少一个分区, 每一 分区被分成多个配向区, 第一配向层 19与第二配向层 29相对应的配向区其 预定的配向方向相互垂直;
在对第一配向层 19与第二配向层 29的各配向区分别采用不同方向的线 偏振光进行照射,对每一配向区照射的线偏振光的偏振方向与配向方向相适 应,从而在第一配向层 19与第二配向层 29上形成具有对应于各配向区的预 定的配向方向的配向月莫。
下面将结合具体的实施例, 首先说明上述第一配向层与第二配向层的配 向原理及过程。
如图 5-图 8所示, 示出了本发明的第一实施例。 在该实施例中, 如图 5 所示, 将 TFT阵列基板 1的第一配向层划分成多个分区 10, 每一分区 10进 一步包括多个配向区 100,在图 5中,每一分区 10由两条互相垂直的分隔线 分成四个配向区 100 (在图中只示出了一个分区 10被划分成四个配向区,此 处仅为举例), 其中, 每一配向区 100 中均被预定有一个配向方向 (见图中 箭头所示),在一个分区 10中至少有两个配向区 100的预定的配向方向不相 同, 其中, 左侧的两个配向区 100的预定配向方向为向上, 而右侧两个配向 区 100的预定配向方向为向下。
同样, 如图 6所示, 将 CF基板 2的第二配向层划分成多个分区 20, 每 一分区 20进一步包括多个配向区 200, 在图 6中, 每一分区 20由两条互相 垂直的分隔线分成四个配向区 200, 其中, 每一配向区 200中均被预定有一 个配向方向(见图中箭头所示), 在一个分区 20中至少有两个配向区 200的 预定的配向方向不相同, 其中, 上侧的两个配向区 200的预定配向方向为向 右, 而下侧两个配向区 200的预定配向方向为向左。
其中, 第一配向层的各配向区 100与第二配向层相对应的各配向区 200 其预定的配向方向相互垂直。
如图 7所示, 示出了利用线偏振光对基板进行照射的示意图。 其中, 该 线偏振光采用紫外线 ( UV ); 图 7中示出了紫外光照射图 6中 CF基板 2的 第二配向层的其中一分区 20中下侧配向区 200的情形。 其中, 箭头方向为 线偏振光的照射方向, 而其上的黑色横线表示线偏振光的偏振方向, 在此实 施例中, 需保证线偏振光的偏振方向与第二配向层的分区 20 中下侧配向区 200的预定配向方向相适应 (例如, 相同), 从而可以通过线偏振光的照射, 可以使该配向区 200形成具有预定配向方向的配向膜。
同理, 需要采用其他不同方向的线偏振光对第二配向层的各分区 20 中 的其他配向区 200进行照射, 以在第二配向层上形成具有预定配向方向的配 向膜; 同时需要采用线偏振光对第一配向层的各分区 10的各配向区 100进 行照射, 以在第一配向层上形成具有预定配向方向的配向膜。
如图 8所示, 示出了本发明提供的一种液晶显示器中第一个实施例中液 晶配向结果示意图。在形成配向膜之后,通过步骤对 TFT阵列基板上的第一 电极和 CF基板上的第二电极通电, 使液晶盒中的液晶分子完成配向。 由于 第一配向层的各配向区 100与相对应的第二配向层上各配向区 200的预定的 配向方向垂直, 故在第一配向层与第二配向层的作用下, 可以使液晶盒中对 应于各配向区的液晶分子产生倒向, 完成配向。 图 8中示出了对应于图 5和 图 6中的一分区处的液晶分子的配向示意图。其最终在第三象限中的液晶分 子与 X轴形成 a度角, 而在第一象限中的液晶分子与 X轴形成 -a度角, 而 在第二角限中的液晶分子与 X轴形成(a-180 )度角, 而在第四角限中的液 晶分子与 X轴形成(180-a )度角, 从而可以改善大视角色偏的问题。 在其 他分区处的液晶分子的配向与此类似。
如图 9-图 11所示,示出本发明的第二个实施例。在该实施例中,在 TFT 阵列基板 1的第一配向层的一个分区 10中, 其上侧两个配向区 100的预定 配向方向为向下, 而下侧两个配向区 100的预定配向方向为向上; 在 CF基 板 2的第二配向的相应分区 20中, 其右侧两个配向区 200的预定配向方向 为向左, 而左侧两个配向区 200的预定配向方向为向右; 最终在液晶显示器 对应的区域的液晶分子在配向结束后均朝向中心位置 (见图 11 ), 其中第一 象限处的液晶分子与 X轴形成 c角度。
如图 12-图 14 所示, 示出本发明的第三个实施例。 在该实施例中, 在 TFT阵列基板 1的第一配向层的一个分区 10中, 其右侧两个配向区 100的 预定配向方向为向右, 而左侧两个配向区 100 的预定配向方向为向左; 在 CF基板 2的第二配向的相应分区 20中, 其上侧两个配向区 200的预定配向 方向为向上, 而下侧两个配向区 200的预定配向方向为向下; 最终在液晶显 示器对应的区域的液晶分子在配向结束后均远离中心位置(见图 14 ), 其中 第一象限处的液晶分子与 X轴形成 b角度。
可以理解的是,上述三个实施例仅为举例,在本发明的其他的实施例中, 第一配向层的各分区中的各配向区的预定配向方向还可以根据需要进行调 动。
其中, 在一个实施例中, 第一电极层 15为像素电极层; 第二电极层 24 为共用电极层。其中,可以将配向层的每个分区大小与 TFT阵列基板 1的一 个像素结构的大小和位置相对应。
以下再具体介绍本发明提供的液晶显示器的结构。 如图 3和图 4所示, 该 TFT阵列基板 1进一步包括:
玻璃基板 11以及设置在该玻璃基板 11上的栅线 13和共用电极 14。 在 栅线 13的上方进一步设置有半导体层 17,在半导体层 17上设置有用于形成 漏极和源极的数据线 12, 然后在其上设置有一层钝化层 180, 在钝化层 180 上形成有像素电极 15 , 第一配向层 19设置在像素电极 15之上。
为了使液晶盒(液晶层) 的上下表面实现平坦化, 需要将彩膜层 18设 置在 TFT P车列基板 1的玻璃基板 11与钝化层 180之间。 通过选用恰当的彩 膜材料, 可以将彩膜层 18当作绝缘层功用, 从而去掉通常放在彩膜层 18上 下表面的绝缘层, 达到了降低成本和提高产能的效果。 彩膜材料包括骨胶, 亚克力, 聚亚酰胺, 聚酯等。 而 CF基板 2具体包括: 玻璃基板 21 , 以及覆盖于玻璃基板 21之上的 共用电极层 24; 其中, 第二配向层 29设置于共用电极层 24之上。
液晶层 3具体包括液晶分子(未示出) 以及间隙子 30。
本发明中, 为防止 TFT阵列基板 1与 CF基板 2之间错位引起像素区域 开口率减小的问题, 在 TFT阵列基板上设置了黑矩阵 22。
如图 4所示, 在本实施例中, 将黑矩阵 22设置于 TFT阵列基板 1的钝 化层 180之上, 而在 CF基板 2上不设置黑矩阵。
图 15为本发明提供的一种液晶显示器的另一个实施例的剖视图; 在该 实施例中, 其与图 4示出的实施例的主要区别在于, 在本实施例中, 其中将 黑矩阵 22设置于 TFT P车列基板 1的玻璃基板 1之上, 栅线 13之下; 而在 CF基板 2上不设置黑矩阵, 其他的结构与图 4中示出的实施例相同, 在此 不进行详述, 可一并参照对图 4的介绍。
图 16为本发明提供的一种液晶显示器的又一个实施例的剖视图。 在该 实施例中, 其与图 4示出的实施例的主要区别在于, 在本实施例中, 将黑矩 阵 22设置于 TFT阵列基板 1的玻璃基板 1之上, 栅线 13的两侧; 而在 CF 基板 2上不设置黑矩阵, 其他的结构与图 4中示出的实施例相同, 在此不进 行详述, 可一并参照对图 4的介绍。
可以理解的是, 在其他的实施例中, 还可以根据需要将黑矩阵 22设置 在 TFT阵列基板 1的其他位置上, 例如, 可以将黑矩阵 22设置于 TFT阵列 基板 1的彩膜层 18与数据线 12之间。 设置的位置可以参照前述的说明, 亦 可以达到相同的效果, 故在此不再贅述。
基于前述有关配向原理、 过程以及液晶显示器结构的介绍, 本发明还提 供该液晶显示器的制造方法。 如图 17所示, 为本发明提供的一种液晶显示 器的制造方法的一个实施例的主流程示意图。 在该实施例中, 该制造方法包 括如下的步骤:
步骤 S10, 提供 TFT阵列基板与 CF基板, 在 TFT阵列基板的玻璃基板 与钝化层之间形成彩膜层,在 TFT阵列基板的第一电极层上涂布偏振光敏感 材料形成第一配向层, 在 CF基板的第二电极层上涂布偏振光敏感材料形成 第二配向层; 步骤 Sll , 将第一配向层与第二配向层均划分成至少一个分区, 各分区 包含多个配向区, 第一配向层与第二配向层相对应的配向区其预定的配向方 向相互垂直;
步骤 S12, 对第一配向层与第二配向层的各配向区分别采用不同方向的 线偏振光进行照射,对每一配向区照射的线偏振光的偏振方向与配向方向相 适应,从而在第一配向层与第二配向上形成具有对应于各配向区的预定的配 向方向的配向月莫;
步骤 S13 , 对 TFT阵列基板上的第一电极层和 CF基板上的第二电极层 通电, 使液晶盒中的液晶分子完成配向;

本发明通过将彩膜层设置于 TFT阵列基板中,这样可以使液晶盒的上下 表面实现平坦化处理, 从而在步骤 S13中获得更好的配向效果。 另外, 通过 选用恰当的彩膜材料, 可以将彩膜层当作绝缘层功用, 从而去掉通常放在彩 膜层上下表面的绝缘层, 达到了降低成本和提高产能的效果。 彩膜材料包括 骨胶, 亚克力, 聚亚酰胺, 聚酯等。
其中, 在一个实施例中, 第一电极层 15为像素电极层; 第二电极层 24 为共用电极层。其中,可以将配向层的每个分区大小与 TFT阵列基板 1的一 个像素结构的大小和位置相对应。

实施本发明, 具有如下的有益效果:
首先, 在本发明的实施例中, 通过在 TFT 阵列基板的第一配向层上和 CF基板的第二配向层上采用不同方向的线偏振光进行照射, 从而形成特定 配向方向配向层, 无需对像素电极进行特别设计, 可以避免现有技术中由于 像素电极导致的暗亮条纹, 从而可以提高光线的透过率; 其次, 在本发明的实施例中, 对第一配向层的各分区中的各配向区的预 以灵活设置, 可以很灵活地实现液晶盒中各像素结构中的四个区域的配向, 同时可以改改善大视角色偏;
第三, 在 TFT阵列基板上设置了黑矩阵, 可以防止 TFT阵列基板与 CF 基板之间因错位引起像素区域开口率减小的问题;
第四, 通过选用恰当的彩膜材料, 可以将彩膜层当作绝缘层功用, 从而 去掉通常放在彩膜层上下表面的绝缘层, 达到了降低成本和提高产能的效 果。
另外, 本发明的实施例中, 将彩膜层设置在 TFT阵列基板上, 可以使液 晶盒(液晶层) 的上下表面实现平坦化, 可以提高液晶配向的效果。
以上所揭露的仅为本发明较佳实施例而已, 当然不能以此来限定本发明 之权利范围, 因此等同变化, 仍属本发明所涵盖的范围。
