图 2是本发明实施例的半透半反液晶显示面板在加电时的结构示意图； 图 3是本发明实施例的半透半反液晶显示面板的反射区垂直取向层的形 成流程示意图。 具体实施方式
本发明的实施例提供了一种半透半反液晶显示面板及其制作方法、 液晶 显示装置， 利用光取向技术制备单盒厚两畴模式的半透半反液晶显示面板， 无摩擦工序， 属于洁净模式， 透射区的第一基板和第二基板以及反射区的第 一基板都采用水平光取向使液晶水平配向， 反射区的第二基板采用垂直光取 向使液晶垂直配向， 这样反射区为混合配向， 混合配向的效果相当于 λ /4位 阻， 透射区为水平配向， 水平配向的效果相当于 λ /2位阻， 从而可以实现半 透半反效果。
图 1示出了本发明实施例所述的半透半反液晶显示面板在未加电时的结 构示意图， 本发明所述的半透半反液晶显示面板的第一实施例包括： 第一基 板 11 , 所述第一基板 11例如可以是对盒基板； 与所述第一基板 11相对设置 的第二基板 12, 所述第二基板 12例如可以是阵列基板， 优选是薄膜晶体管 阵列基板； 以及设置于所述第一基板 11和所述第二基板 12之间的包括多个 液晶分子 13的液晶层；
所述第一基板 11和所述第二基板 12之间包括： 透射区和反射区； 所述透射区的液晶层厚度等于所述反射区的液晶层厚度；
所述第一基板 1 1上设置有第一水平取向层 14;
所述第二基板 12 上对应于所述透射区的区域设置有与所述第一水平取 向层 14相对的第二水平取向层 15;
所述第二基板 12 上对应于所述反射区的区域设置有与所述第一水平取 向层 14相对的垂直取向层 16;
例如， 所述第一水平取向层 14、 所述第二水平取向层 15和所述垂直取 向层 16采用聚酰亚胺（Polymide, PI )材料。
例如，所述垂直取向层采用光接枝实现，所述垂直取向层 16表面还形成 有光接枝链 17;
例如，所述第二基板 12上对应于所述反射区的区域设置有位于所述垂直 取向层 16的背向所述液晶层的一面的反射层 18。
在本发明的实施例的半透半反液晶显示面板的第一实施例中， 透射区的 液晶层厚度等于所述反射区的液晶层厚度， 但是本发明的实施例半透半反液 晶显示面板也可以应用于双盒厚的情况下。
本发明实施例的半透半反液晶显示面板的第一实施例中， 第一基板上设 置有第一水平取向层； 第二基板上对应于所述透射区的区域设置有与所述第 一水平取向层相对的第二水平取向层； 第二基板上对应于所述反射区的区域 设置有与所述第一水平取向层相对的垂直取向层， 透射区的第一基板和第二 基板， 以及反射区的第一基板都采用水平光取向使液晶水平配向， 反射区的 第二基板采用垂直光取向使液晶垂直配向， 无摩擦工序， 属于洁净模式， 无 污染、 不产生静电、 并易实现分区取向， 并且反射区为混合配向， 混合配向 的效果相当于 λ/4位阻， 透射区为水平配向， 水平配向相当于 λ/2位阻， 从 而可以实现半透半反效果。
设定所述透射区的液晶层厚度和所述反射区的液晶层厚度都为 d;
上述实施例所述的半透半反液晶显示面板在显示时， 透射区的液晶层产 生的相位延迟量为： dxAnl ,反射区的液晶层产生的相位延迟量为 2xdxAn2, 其中， Δηΐ 为光线经过透射区的液晶时产生的相位延迟， Δη2 为光线经过 反射区的液晶时产生的相位延迟。
要实现半透半反显示， 光线通过透射区的液晶层产生的相位延迟量和光 线通过反射区域的液晶层产生的相位延迟量要匹配。而由于在上述实施例中， 反射区为混合配向， 混合配向的效果相当于 λ/4位阻， 透射区为水平配向， 水平配向相当于 λ/2位阻， 因此 Δηΐ为 Δη2的两倍， 所以透射区的液晶层产 生的相位延迟量等于反射区的液晶层产生的相位延迟量， 可以实现半透半反 显示。
在上述的半透半反液晶显示面板中，所述第一基板 1 1的背向所述液晶层 的一面上设置有第一偏振片 19 , 以及所述第一偏振片 19与所述第一基板 1 1 之间设置有第一 λ/4相位延迟板 110;
所述第二基板 12的背向所述液晶层的一面上设置有第二偏振片 11 1 ,以 及所述第二偏振片 1 1 1与所述第二基板 12之间设置有第二 λ/4相位延迟板 1 12;
所述第一偏振片 19的透光轴与所述第二偏振片 1 11的透光轴平行，所述 第一 λ/4相位延迟板 1 10的光轴与该透光轴成 45。，所述第二 λ/4相位差板 1 12 的光轴与该透光轴成 45°;
所述第一偏振片 19和所述第二偏振片 11 1可以为 0度偏振片或 90度偏 振片。
图 2是本发明实施例的半透半反液晶显示面板在加电时的结构示意图。 未施加电场时， 入射光在反射区与透射区均以 π位相差通过偏振片， 半 透半反液晶显示面板显示亮态。 施加一定的电压时， 液晶层引起的相位差消 失，反射区入射光线两次通过 λ/4相位延迟板 1 10后偏转 90。，被所述第一偏 振片 19阻隔， 透射区光线也是通过 λ/4相位延迟板 112和 1 10后偏转 90° , 被所述第一偏振片 19阻隔， 半透半反液晶显示面板显示暗态。
上述液晶面板在实现显示的过程中， 未施加电场时， 透射区和反射区均 呈亮态：
在反射区内， 由于第一偏振片 19的透光轴方向沿竖直方向，所以环境光 通过第一偏振片 19, 产生竖直方向的线偏振光， 并经过第一 λ/4相位延迟板 1 10, 从而产生左旋圓偏振光；
左旋圓偏振光两次通过液晶层后， 经过 λ/2相位延迟， 变为右旋圓偏振 光， 该右旋圓偏振光经过第一 λ/4相位延迟板 1 10, 从而变成竖直方向线偏 振光， 由于此时竖直方向线偏振光的偏振方向与第一偏振片 19 的透光轴平 行， 从而形成反射区域的亮态；
在透射区内， 从背光源发出的光线经过第二偏振片 111 , 由于第二偏振 片 111的透光轴沿竖直方向， 光线通过第二偏振片 111时， 产生竖直方向线 偏振光， 并经过第二 λ/4相位延迟板 112, 从而产生左旋圓偏振光， 左旋圓 偏振光通过液晶层， 经过 λ/2相位延迟， 变为右旋圓偏振光， 该右旋圓偏振 光经过第一 λ/4相位延迟板 110, 从而变成竖直方向线偏振光， 由于此时竖 直方向线偏振光的偏振方向与第一偏振片 19的光透过轴平行,从而形成透射 区域的亮态。
在液晶面板施加电压时， 液晶层引起的相位差消失， 透射区和反射区均 呈暗态：
在反射区内， 由于第一偏振片 19的光透过轴方向沿竖直方向，环境光通 过第一偏振片 19, 产生竖直方向线偏振光， 并经过第一 λ/4相位延迟板 110, 从而产生左旋圓偏振光， 左旋圓偏振光经过液晶层， 由于液晶层引起的相位 差消失， 因此左旋圓偏振光再次通过第一 λ/4相位延迟板 110, 变成水平方 向线偏振光， 由于此时水平方向线偏振光的偏振方向与第一偏振片的光透过 轴垂直， 从而形成透射区域的暗态；
在透射区内， 从背光源发出的光线经过第二偏振片 111 , 由于第二偏振 片 111的光透过轴沿竖直方向， 光线通过第二偏振片 111时， 产生竖直方向 线偏振光， 并经过第二 λ/4相位延迟板 112, 从而产生左旋圓偏振光， 左旋 圓偏振光通过液晶层， 由于液晶层引起的相位差消失， 该左旋圓偏振光经过 第一 λ/4相位延迟板 110, 从而变成水平方向线偏振光， 由于此时水平方向 线偏振光的偏振方向与第一偏振片 19的光透过轴垂直，从而形成透射区域的 暗态。
本发明的实施例还提供了一种液晶显示装置， 包括本发明实施例的上述 半透半反液晶显示面板。
本发明实施例还提供了一种半透半反液晶显示面板的制作方法， 所述半 透半反液晶显示面板包括： 第一基板； 与所述第一基板相对设置的第二基板； 设置于所述第一基板和所述第二基板之间的液晶层； 所述半透半反液晶显示 面板在一个像素域内包括透射区和反射区； 其中， 该半透半反液晶显示面板 的制作方法可以包括： 步骤 31 : 提供第一基板；

步骤 35:在所述第二基板上对应于所述反射区的区域形成与所述第一水 平取向层相对的垂直取向层；
步骤 36: 形成液晶层于所述第一基板和所述第二基板之间。
通过上述半透半反液晶显示面板的制作方法可以制作出如图 1所示的结 构， 下面结合上述步骤以及图 3对本发明实施例的半透半反液晶显示面板的 制作方法进行进一步的介绍：
步骤一： 提供第一基板；
步骤二： 在所述第一基板上涂覆水平配向的第一取向液； 例如， 所述第 一取向液为 PI(Polymide, 聚酰亚胺)液；
步骤三： 对所述第一取向液进行光取向以形成所述第一水平取向层； 步骤四： 如图 3所示， 提供第二基板 12;
步骤五： 在所述第二基板上涂覆水平取向的第二取向液 42; 例如， 所述 第二取向液为 PI(p0lymide, 聚酰亚胺)液；
步骤六： 使用紫外光掩膜 ( UV mask ) 41将所述第二基板 12上对应于 所述反射区的区域掩盖；
步骤七： 采用紫外光（UV )偏振光对所述第二基板 12上对应于所述透 射区的区域进行水平配向，在所述第二基板 12上对应于所述透射区的区域上 形成第二水平取向层 15;
由于透射区是 ecb (电控双折射）模式， 需要平行取向， 因此必须采用 偏振光才能实现液晶分子在一定方向上的取向；
步骤八:去除所述第二基板 12上对应于所述反射区的区域上的紫外光掩 膜 41 ,使用紫外光掩膜 43将所述第二基板 12上对应于所述透射区的区域掩 盖；
在操作时，可以将所述第二基板 12上对应于所述反射区的区域上的紫外 光掩膜绕所述第二基板的中心旋转 180度，以将所述第二基板 12上对应于所 述透射区的区域掩盖；
步骤九：在所述第二基板 12上对应于所述反射区的区域喷涂混合液 44, 采用非偏振紫外光对所述第二基板 12上对应于所述反射区的区域曝光，以形 成与所述第一水平取向层相对的垂直取向层 16; 例如， 所述垂直取向层 16 采用光接枝实现， 所述垂直取向层 16表面还形成有光接枝链 17;
由于在反射区需进行光接枝， 所以液晶分子不需要沿特定方向取向， 只 需要形成降解点就可以， 因此需采用非偏振紫外光；
在操作时， 可以在所述第二基板 12 对应于反射区的区域旋转喷涂混合 液；
例如， 所述混合液包括光敏剂、 偶氮引发剂和亚克力单体； 所述混合液 由光敏剂、 偶氮引发剂以及亚克力单体按一定比例混合而成；
步骤十： 去除该紫外光掩膜 43。
在本发明实施例的半透半反液晶显示面板的制作方法的示例中， 第一基 板采用 PI液水平光配向， 第二基板上对应于透射区的区域也采用 PI液水平 光配向； 第二基板的反射区采用垂直配向，垂直配向可以采用 PI表面光接枝 实现。 先用紫外光掩膜将所述第二基板上对应于所述反射区的区域掩盖， 采 用紫外光偏振光对所述第二基板上对应于所述透射区的区域进行水平配向， 然后将所述紫外光掩膜绕所述第二基板的中心旋转 180度， 在所述第二基板 对应于反射区的区域旋转喷涂混合液， 所述混合液由光敏剂、 偶氮引发剂以 及亚克力单体按一定比例混合而成， 然后采用非偏振紫外光照射进行光接枝 反应使 PI主链上形成垂直取向侧链，这样制备的液晶显示面板中反射区为混 合配向， 混合配向的效果相当于 λ/4位阻， 水平配向相当于 λ/2位阻， 从而 可以实现半透半反效果。 并且在本发明实施例的半透半反液晶显示面板的制 作方法的示例中， 透射区的第一基板和第二基板以及反射区的第一基板都采 用水平光取向使液晶水平配向， 反射区的第二基板采用垂直光取向使液晶垂 直配向， 无摩擦工序， 属于洁净模式， 无污染、 不产生静电、 并易实现分区 取向。 以上所述是本发明的一些实施方式， 应当指出， 对于本技术领域的普 通技术人员来说， 在不脱离本发明所述原理的前提下， 还可以作出若干改进 和润饰， 这些改进和润饰也应视为本发明实施例的保护范围。
