实施例一
本发明实施例一提供一种液晶显示面板， 包括： 阵列基板 1、彩膜基板 2、 阵列基板 1和彩膜基板 2对盒形成液晶盒 3 , 以及液晶盒 3内灌注的液晶。本 发明实施例中在阵列基板 1面向彩膜基板 2—侧设置有多畴水平取向液晶层 4, 如图 1所示。
例如， 本发明实施例中阵列基板 1 上设置有多畴取向的电极结构， 如图 2A所示为设置有多畴取向的电极结构的阵列基板俯视图。
进一步的， 本发明实施例中阵列基板 1的内侧， 即阵列基板 1面向彩膜 基板 2的一侧，设置有多畴水平取向液晶层 4, 多畴水平取向液晶层 4包括聚 合物液晶混合物， 可聚合液晶混合物在电场的作用下， 能够使液晶分子 8按 照电场的方向进行排列， 因此本发明实施例中可对多畴取向的电极施加电压 V,使可聚合液晶混合物的液晶分子 8在阵列基板 1所在平面上，按照阵列基 板 1上电极的畴向进行多畴水平取向排列，即可聚合液晶混合物的液晶分子 8 可通过一次取向形成多畴取向， 如图 2B所示为设置有多畴水平取向液晶层 4 的阵列基板俯视图。
进一步的， 本发明实施例中聚合物液晶混合物包括聚合液晶分子和反应 基团（ RM基团），例如，聚合液晶分子和 RM基团的质量百分比比例为（ 90±5 ) %: ( 10士 5 ) %, 也可选用其他比例， 并不引以为限。
可聚合液晶分子在电场作用下能够按照电场方向进行排列， 本发明实施 例中采用可聚合液晶混合物作为形成多畴水平取向液晶层的材料， 阵列基板 上形成有多畴取向的电极结构， 故当给阵列基板的电极施加电压并通电时， 则可使原有自由排列的可聚合液晶分子按照电极的多畴取向进行多畴水平取 向排列， 通过一次取向实现液晶分子 8的多畴取向， 工艺筒单， 可操作性强。
本发明实施例提供的液晶显示面板， 在阵列基板上设置包括有聚合物液 晶混合物的多畴水平取向液晶层， 多畴水平取向液晶层的液晶分子 8在电场 的作用下能够按照阵列基板上的多畴电极的畴向实现多畴取向， 通过一次取 向即可实现多畴取向， 工艺操作筒单， 可操作性强。
实施例二
ADS多畴模式的透明显示装置， 需要实现液晶盒的透明态与不透明态， 本发明实施例二将对应用实施例一中涉及的在阵列基板内侧一次取向形成多 畴水平取向液晶层的液晶显示面板， 实现透明显示装置的透明态与不透明态， 做更为详细的说明。
如图 3A所示， 本发明实施例二提供的液晶显示面板包括： 阵列基板 1、 彩膜基板 2、设置在阵列基板 1面向彩膜基板 2—侧的多畴水平取向液晶层 4、 设置在彩膜基板 2面向阵列基板 1的一侧并具有垂直取向的取向膜 5 , 其中， 垂直取向指取向方向垂直彩膜基板 2所在的平面， 以及由阵列基板 1与彩膜 基板 2对盒形成液晶盒 3 , 液晶盒 3内灌注有液晶分子 8。
本实施例中在彩膜基板 2的内侧， 即彩膜基板 2面向阵列基板 1的一侧 设置垂直取向的取向膜 5。 阵列基板 1内侧设置有多畴水平取向液晶层 4。 在 阵列基板的电极未被施加电压即未通电时， 由上述阵列基板 1 与彩膜基板 2 对盒形成的液晶盒 3 内的液晶分子将按照彩膜基板内侧的取向膜 5的取向方 向和阵列基板内侧的多畴水平取向液晶层 4液晶分子的取向方向进行取向， 彩膜基板 2 内侧的取向膜具有垂直取向， 使得液晶盒内靠近取向膜一侧的液 晶分子 8也具有垂直取向。 而阵列基板 1一侧多畴水平取向液晶层 4的液晶 分子具有多畴的水平取向， 使得液晶盒内靠近阵列基板 1 一侧的液晶分子具 有多畴的水平取向， 即液晶盒内的液晶分子具有混合取向， 光不能透过液晶 盒， 液晶盒处于不透明态。 即在没有外加电源时， 液晶盒内的液晶分子具有 使液晶盒处于不透明态的混合取向，可再次参阅图 1。本发明实施例中通过使 阵列基板附近的液晶盒内液晶分子 8多畴的水平取向， 彩膜基板附近的液晶 盒内液晶分子垂直取向， 使得液晶盒内的液晶分子混合取向， 混合取向的液 晶分子， 使得从背光过来的光线完全不能透过液晶盒， 实现透明显示装置的 不透明态。 并且由于彩膜基板一侧垂直取向， 阵列基板一侧水平取向， 使得 暗态情况下的亮度很低， 实现了较高的对比度， 进而提高了显示品质。
本实施例中在彩膜基板 2的内侧， 即彩膜基板 2面向阵列基板 1的一侧 设置垂直取向的取向膜 5 , 阵列基板 1内侧设置有多畴水平取向液晶层， 当阵 列基板上的电极被施加电压即通电时， 液晶盒内的液晶分子 8在电场的作用 下， 会按照电场的方向进行排列， 不再是具有垂直取向和水平取向的混合取 向， 这时使得光可以透过液晶盒， 该液晶盒呈现透明态。 即在有外加电压时， 液晶盒内的液晶分子 8具有使液晶盒处于透明态的取向。
进一步的， 如图 3B所示， 本实施例中多畴水平取向液晶层包括有可聚合 液晶分子和反应基团， 使得液晶盒内的液晶分子和多畴水平取向液晶层内的 可聚合液晶分子以及反应基团之间的极性作用力很大， 增大了多畴水平取向 液晶层对其表面液晶分子的锚定力。 在有外加电源时， 透明显示装置实现透 明态时， 液晶盒内的液晶分子除受到电场作用以外， 还会受到阵列基板上多 畴水平取向液晶层的强锚定作用， 从而使得液晶盒内的液晶分子在沿电场方 向排列的同时， 还具有沿阵列基板上多畴水平取向液晶层中液晶分子多畴水 平取向方向多畴分布的趋势， 从而增强透明显示装置的多视角特性。
本实施例中使用含有 RM基团和可聚合液晶分子的可聚合液晶混合物对 阵列基板进行多畴取向， 能够通过一次取向形成多畴取向， 工艺筒单。 进一 步的， 在阵列基板上设置多畴水平取向液晶层的同时， 在彩膜基板内侧设置 垂直取向的取向膜， 在多畴模式上使用混合取向技术实现透明显示装置的透 明态与不透明态， 能够在不使用偏光片情况下得到较好的显示品质。
实施例三
本发明实施例三提供另一种应用实施例一中涉及的在阵列基板内侧一次 取向形成多畴水平取向液晶层的液晶显示面板， 实现透明显示装置的透明态 与不透明态。
本发明实施例三提供的液晶显示面板包括： 阵列基板 1、 彩膜基板 2、 分 别设置在阵列基板 1面向彩膜基板 2一侧和彩膜基板 2面向阵列基板 1的一 侧的多畴水平取向液晶层 4、以及由阵列基板 1与彩膜基板 2对盒形成的液晶 盒 3 , 液晶盒 3内灌注有液晶。
例如， 为实现透明显示装置的透明态和不透明态， 本实施例中在阵列基 板 1和彩膜基板 2背向液晶盒的一侧分别设置第一偏光片 6和第二偏光片 7, 并且第一偏光片 6的偏光方向和第二偏光片 7的偏光方向垂直设置， 在没有 外加电源的时候， 虽然靠近彩膜基板一侧的液晶分子和靠近阵列基板一侧的 液晶分子 8取向方向相同， 但是因为第一偏光片的偏光方向和第二偏光片的 偏光方向相互垂直，使得光线也不能通过液晶盒 3 , 因此液晶盒 3处于不透明 态， 如图 3C所示。 而当有外加电源的时候， 虽然多畴水平取向的液晶层表面 的液晶分子 8因为锚定作用保持原来的状态， 但是液晶盒 3 内的大部分液晶 分子 8会按照电场方向进行排列， 实现液晶分子 8的偏转，偏转的液晶分子 8 具有使光线能够透过偏光片偏光轴的角度， 进而使得光线能够透过液晶盒 3 , 使得透明显示装置处于透明态。 并且为了增大透过率， 可以旋转第一偏光片 和第二偏光片使液晶分子达到所需的透过率值， 操作灵活， 如图 3D所示。
本发明实施例三提供的透明显示面板， 在彩膜基板 2与阵列基板 1上都 设置多畴水平取向液晶层 4,无需单独设置取向膜， 并能一次取向即实现透明 显示装置的透明态和不透明态， 可筒化制作工艺。
实施例四
本发明实施例四提供一种液晶显示面板的制作方法， 实现过程如图 4所 示， 包括：
S101 : 制作阵列基板和彩膜基板。
本发明实施例中的阵列基板可采用常规的阵列制作工艺制作。 制作的阵 列基板可以是多种类型的， 但制作的阵列基板需包括有多畴取向的电极结构， 例如可以是 ADS多畴模式的阵列基板， 如图 5A所示为本发明实施例提供的 ADS多畴模式阵列基板结构示意图。
将采用完整的阵列工艺制作好的具有多畴取向电极结构的阵列基板清洗 后待用。
本发明实施例中的彩膜基板也可采用常规的制作工艺制作。 S102: 在 S101中制作的阵列基板内侧分散设置可聚合液晶混合物。 本发明实施例中在阵列基板内侧形成可聚合液晶混合物可采用涂覆方 式、 转印方式或者旋涂等方式， 在此不做限定。
进一步的， 本发明实施例中在阵列基板内侧形成的可聚合液晶混合物， 由于没有电场的作用， 可聚合的液晶分子在具有多畴取向电极结构的阵列基 板上自由排列， 如图 5B所示。
本发明实施例中可聚合液晶混合物例如为可聚合液晶分子和反应基团的 混合物， 其中吸电子基团是含有较大电负性的基团， 例如 -CN; -X (X 为 卤族元素）等， 控制可聚合液晶分子和所述反应基团的质量百分比比例为 ( 90±5 ) %: ( 10±5 ) %。 分散排列包括有可聚合液晶分子和反应基团的可聚 合液晶混合物。 进一步的， 本发明实施例中可聚合液晶混合物还可以是由包含有可聚合 官能团的液晶单体组成。
S103: 对 S102中的阵列基板施加电压， 使可聚合液晶混合物的液晶分子 进行多畴排列。
本发明实施例中对阵列基板外加电源， 施加电压后， 由于阵列基板的电 极具有多畴取向， 因此也会产生相应的电场方向， 进而会使形成在阵列基板 上的自由排列的可聚合液晶分子按照电场的方向进行多畴排列， 如图 5C 所 示。
S104: 对经过步骤 S103的阵列基板进行固化处理， 形成包括聚合物液晶 混合物的多畴水平取向液晶层。
本发明实施例对阵列基板进行固化处理时， 固化波长与可聚合液晶混合 物的聚合波长一致。 一般可聚合液晶混合物的可聚合波长处在紫外区， 为
360nm 左右。 本发明实施例可聚合波长例如为 360nm。 聚合能量例如为 lmw/cm2。 聚合时间里如为 1 小时。 固化后形成多畴水平取向液晶层， 如图
5D所示。
S105: 将彩膜基板和形成有多畴水平取向液晶层的阵列基板对盒， 如图 5E所示， 并填注液晶， 形成液晶显示面板。
进一步的， 本发明实施例中如图 5E所示的液晶显示面板， 在不加电的时 候， 光不能透过液晶盒 3 , 即液晶盒 3为不透明态， 如图 6所示。 在加电的时 候，液晶盒 3内的液晶分子 8在电场的作用下进行排列，光可以透过液晶盒 3 , 该液晶盒 3为透明态， 如图 7所示。
例如， 本发明实施例中， 在执行步骤 S105之前， 一方面可在 S101中制 作好的彩膜基板上形成取向方向垂直阵列基板所在平面的取向膜， 形成实施 例二所涉及的透明显示装置中的液晶显示面板。 另一方面还可在 S101中制作 好的彩膜基板上形成液晶分子取向方向与阵列基板上多畴水平取向层液晶分 子取向方向反向平行的多畴水平取向液晶层， 且彩膜基板的多畴水平取向液 晶层的畴向与述阵列基板上的多畴水平取向液晶层的畴向相同， 即在彩膜基 板上形成与阵列基板上畴数相同、取向方向反向平行的多畴水平取向液晶层， 如图 8所示。 并在执行步骤 S105之后， 在彩膜基板与阵列基板背向液晶盒的 一侧分别设置第一偏光片和第二偏光片， 并使得第一偏光片与第二偏光片相 互垂直， 形成实施例三所涉及的透明显示装置中的液晶显示面板。
本发明实施例对在彩膜基板一侧形成与阵列基板上畴数相同、 取向方向 反向平行的多畴水平取向液晶层的方式并不做限定， 可以采用多种方式实现， 例如， 可在彩膜基板一侧设置与阵列基板上一致的电极层级结构， 并对彩膜 基板施加电压进而使可聚合液晶混合物的液晶分子进行多畴排列， 形成最终 所需的多畴水平取向液晶层。
需要说明的是， 本发明实施例中制作形成有垂直取向膜或多畴水平取向 液晶层的彩膜基板和形成有多畴水平取向液晶层的阵列基板的顺序并不分先 后。
本发明实施例提供的液晶显示面板制作方法， 在阵列基板上形成可聚合 的液晶混合物， 并通过外加电源使可聚合液晶分子按照电极的方向进行多畴 排列， 形成多畴水平取向液晶层， 通过一次取向实现多畴取向， 并对彩膜基 板上设置垂直取向的取向膜或多畴水平取向液晶层， 在一次取向的基础上实 现透明显示装置的透明态和不透明态， 筒化了制作工艺， 可操作性强， 并且 避免了工艺不良造成的显示品质下降的不足。
