在本公开中， "同层设置" 是针对至少两种图案而言的。 至少两种图案 同层设置是指： 将同一薄膜通过构图工艺形成至少两种图案。 例如， 上述同 层设置的像素电极和公共电极是指： 由同一透明导电薄膜通过构图工艺形成 的像素电极和公共电极。 像素电极是指通过开关单元（例如， 薄膜晶体管） 与数据线连接的电极， 被施加数据信号电压； 公共电极是指和公共电极线连 接的电极， 被施加公共电压。
下面参考图 3 ,针对设置在第一基板 11内侧的像素区域的像素结构进行 更详细地描述。 如图所示， 所述像素区域还设置有薄膜晶体管。 例如， 该薄 膜晶体管的栅极 303a, 源极 303b和漏极 303c分别电连接所述栅线 300、 所 述数据线 301和像素电极 304。 公共电极 305和公共电极线（图中未示出） 相连。 这样在通电情况下， 数据线 301可以通过薄膜晶体管 303向像素电极 304施加电压， 公共电极 305由公共电极线提供电压， 使得像素电极 304与 公共电极 305间产生水平电场， 以驱动蓝相液晶面板。

在本公开中， 透射区是指来自背光的光依次透过第一基板、 蓝相液晶层 以及第二基板而射出的区域； 反射区是指设置有反射层 31 的区域， 在反射 区来显示面板外的环境光依次经第二基板、 蓝相液晶层至反射层， 经反射层 反射后， 再经蓝相液晶层、 第二基板而射出。
在所述反射区，所述第一基板的内侧还设置有反射层 31 ; 且在所述反射 层 31上还设置有绝缘层 32 ,所述绝缘层 32同时延伸于所述透射区和反射区。 优选的，所述绝缘层 32在透射区的厚度大于所述绝缘层 32在反射区的厚度， 且所述绝缘层在两区域厚度之差为所述反射层的厚度。这样能够保证设置有 绝缘层的蓝相液晶面板仍为单盒厚， 即在反射区和透射区的蓝相液晶层厚度 一致。
上述蓝相液晶层中包含有蓝相液晶分子， 其特性为： 在不施加电压时， 蓝相液晶分子具有各向同性特性； 在施加电压时， 蓝相液晶分子则沿着一个 方向具有双折射特性， 并且蓝相液晶分子沿电场的方向配向。 由于上述蓝相 液晶层的这种特性，故而在本发明实施例中利用像素电极和公共电极所能够 产生的水平电场驱动蓝相液晶面板。该蓝相液晶例如为聚合物稳定的蓝相液 晶等。
本公开中， 构图工艺例如为光刻构图工艺， 例如包括： 在需要被构图的 结构层上涂覆光刻胶层， 使用掩膜板对光刻胶层进行曝光， 对曝光的光刻胶 层进行显影以得到光刻胶图案， 使用光刻胶图案对结构层进行蚀刻， 然后可 选地去除光刻胶图案。 构图工艺还可以是丝网印刷、 喷墨打印方法等。
上述位于所述透射区的相邻条状电极的间距小于位于所述反射区的相 邻条状电极的间距， 两者的比例关系的确定与所釆用的蓝相液晶的性质（如 双折射率性质， 介电各向异性性质， 科尔常数等）相关。 例如， 可以按照以 下测试方法针对包含特定蓝相液晶的面板进行测试， 以确定两间距的比例关 系。 首先， 按照预先设定的几个间距比值制造不同的测试面板， 并且这些测 试面板中均填充上述特定的蓝相液晶。 其次， 绘制这几个测试面板的透射区 和反射区的 V-T (电压-透过率 )曲线特性， 若一测试面板的透射区和反射区 的曲线特性在误差范围内一致， 则说明透射区的相位延迟大致为反射区的相 位延迟的 2倍，那么该测试面板的比例关系就可以作为实际生产中的参考值。 在本发明实施例中对上述比值不加限定， 而以实际生产中能够使得同一个像 素区域的透射区、反射区中用于显示的光线通过所述蓝相液晶层所产生的相 位延迟量相同为准。
在一个示例中， 上述蓝相液晶面板可以还包括： 设置在所述第一基板 11 外侧的第一四分之一波片 23、 第一二分之一波片 22以及第一偏振片 21 ; 设 置在所述第二基板 12外侧的第二四分之一波片 24、 第二二分之一波片 25 以及第二偏振片 26。
在该示例中， 例如， 在所述第一基板 11 的外侧， 从内至外依次设置有 第一四分之一波片 23、 第一二分之一波片 22以及第一偏振片 21 ; 在所述第 二基板 12的外侧， 从内至外依次设置有第二四分之一波片 24、 第二二分之 一波片 25、 以及第二偏振片 26。
下面， 以上述 IPS型显示器的蓝相液晶面板如何实现半透半反显示为例 进行详述。
图 1为蓝相液晶面板在不加电时的结构示意图。 由于不加电压时， 蓝相 液晶层中的蓝相液晶分子是各向同性的， 而透射区、 反射区中用于显示的光 线经过各向同性的蓝相液晶层 13不会产生相位延迟量。若第一偏振片 21和 第二偏振片 26的偏振方向呈 90度夹角， 出射光线会被第二偏振片 26完全 挡住， 从而实现暗态的显示。
图 2为蓝相液晶面板在加电时的结构示意图。蓝相液晶分子在水平电场 作用下， 产生水平方向的相位延迟， 位于透射区的相邻条状电极的间距 dl 与位于反射区的相邻条状电极的间距 d2不同， 且 dl<d2。 由于位于透射区 的相邻条状电极的间距 dl较小， 将产生较强的电场强度， 所以蓝相液晶分 子在较强的电场作用下会产生较大的相位延迟 Δ η1。 反之， 由于位于反射区 的相邻条状电极的间距 d2较大， 将产生较弱的电场强度， 所以蓝相液晶分 子在较弱的电场作用下会产生较小的相位延迟 Δ η2。 由于反射层 31 的反射 作用， 反射区的光线会两次通过蓝相液晶层， 所以反射区的光线经过蓝相液 晶层的传播距离 D2约为透射区的光线经过蓝相液晶层的传播距离 D1 的 2 倍， 即大概 D2=2*D1。 于是， 可以通过优化位于透射区和反射区的相邻条状 电极的间距 dl和 d2 , 使得同一个像素区域的透射区、 反射区中用于显示的 光线通过所述蓝相液晶层所产生的相位延迟量相同， 即为 Δ ηΐ *D1= A n2*D2, 以达到半透半反的显示效果。
对于上述提供的 ADS型显示器中的蓝相液晶面板如何实现半透半反显 示可以参考上述原理， 在此不加赘述。
本发明实施例提供的透反式蓝相液晶面板为单盒厚，通过将像素区域中 位于透射区的相邻条状电极的间距小于位于反射区的相邻条状电极的间距， 使得透射区、反射区中用于显示的光线通过所述蓝相液晶层所产生的相位延 迟量相同， 从而实现单盒厚的透反式蓝相液晶面板。 由于本发明实施例中釆 用的是单盒厚的结构， 故可简化制作工艺的难度。
参考图 4-图 6、 图 10-图 12 , 本发明实施例还提供了一种蓝相液晶显示 面板， 该液晶面板包括： 彼此对置以形成液晶盒的第一基板 11 和第二基板 12, 以及位于两基板间的蓝相液晶层 13。 该蓝相液晶面板还包括： 位于所述 第一基板 11内侧的栅线 600、与所述栅线交叉设置以限定像素区域的第一数 据线 601、 第二数据线 602。 所述栅线与所述第一数据线、 第二数据线所限 定了多个按照阵列排列的像素区域， 每个像素区域可分为透射区和反射区。 下面的描述针对单个像素区域进行。
该实施例的蓝相液晶面板也为单盒厚。 所述蓝相液晶面板还包括： 位于 整个像素区域（即反射区和透射区） 的公共电极 607 , 位于所述透射区的第 一像素电极 605和位于所述反射区的与所述第一像素电极同层设置的第二像 素电极 606。 所述公共电极 607和所述像素电极 (包括第一像素电极 605和 第二像素电极 606 ) 至少之一包括多个条状电极。 在通电情况下， 由第一数 据线 601、 第二数据线 602分别向第一像素电极 605、 第二像素电极 606施 加不同电压，使得位于同一像素区域的第一像素电极 605和公共电极 607间 的压差大于第二像素电极 606和公共电极间 607的压差， 以使透射区、 反射 区中用于显示的光线通过所述蓝相液晶层所产生的相位延迟量相同。 例如， 优选地同一层的位于透射区的相邻条状电极间距和位于反射区的相邻条状 电极目同。
图 4-图 6是一种 IPS型液晶显示器的液晶面板， 图 10-图 12为 ADS型 液晶显示器的液晶面板。
例如， 图 4-图 6所示， 上述公共电极包括多个条状电极， 所述像素电极 包括多个条状电极。 所述公共电极 607和所述像素电极（包括第一像素电极 605和第二像素电极 606 ) 同层设置， 所述第一像素电极 605包含的条状电 极和位于所述透射区的公共电极 607包含的条状电极间隔设置， 所述第二像 素电极 606包含的条状电极和位于所述反射区的公共电极 607包含的条状电 极间隔设置。
下面参考图 6 , 针对上述液晶面板中设置在第一基板内侧的像素结构进 行详述。上述蓝相液晶面板还包括位于像素区域的第一薄膜晶体管 603和第 二薄膜晶体管 604。 由第一数据线 601、 第二数据线 602分别向第一像素电 极 605、 第二像素电极 606施加不同电压例如由如下方式实现。 由第一数据 线 601通过所述第一薄膜晶体管 603向所述第一像素电极 605施加第一电压； 由第二数据线 602通过所述第二薄膜晶体管 604向所述第二像素电极 606施 加第二电压， 且第一电压与第二电压不相等。
具体的， 所述第一薄膜晶体管的栅极 603a, 源极 603b和漏极 603c分别 电连接所述栅线 600、 所述第一数据线 601和所述第一像素电极 605; 所述 第二薄膜晶体管的栅极 604a, 源极 604b和漏极 604c分别电连接所述栅线 600、 所述第二数据线 602和所述第二像素电极 606。 这样在通电情况下， 第 一数据线 601可以向第一像素电极 605施加第一电压， 第二数据线 602可以 向第二像素电极 606施加第二电压。 优选的， 所述第一数据线 601和所述第 二数据线 602分置于所述像素区域的两侧。
可选的， 参考图 10-图 12, 上述公共电极和所述像素电极至少之一包括 多个条状电极。 所述公共电极和所述像素电极异层设置， 也就是说， 第一像 素电极 605和第二像素电极 606同层设置， 并且这两个像素电极和公共电极 异层设置。所述公共电极和所述像素电极中位于上层的电极包括多个条状电 极， 位于下层的电极为平板电极。 图中以像素电极位于上层， 公共电极位于 下层为例， 当然， 也可以公共电极位于上层， 像素电极位于下层。
图 12所示的像素结构和图 6所示的像素结构中的薄膜晶体管与栅线、 第一和第二数据线之间的连接关系相同， 在此不加赘述。 不同的是， 图 12 中的位于透射区的第一像素电极的相邻条状电极间距和位于反射区的第二 像素电极的相邻条状电极间距相同。 同样， 优选的， 所述第一数据线 601和 所述第二数据线 602分置于所述像素区域的两侧。
或者， 所述公共电极和所述像素电极异层设置， 而且所述公共电极和所 述像素电极均包括多个条状电极。 虽然图中未示出， 本领域技术人员参考图 10-图 12能够毫无疑义的确定这种液晶面板的结构。 在这种液晶面板中第一 像素电极的相邻条状电极间距和第二像素电极的相邻条状电极间距相同， 并 且，公共电极位于透射区的相邻条状电极的间距和位于反射区的相邻条状电 极间距相同。
在上述液晶显示面板的反射区， 所述第一基板的内侧还设置有反射层
31 ; 且在所述反射层 31上设置有绝缘层 32,所述绝缘层 32同时延伸于所述 透射区和反射区； 优选的， 所述绝缘层 32在透射区的厚度大于所述绝缘层 32在反射区的厚度， 且所述绝缘层在两区域厚度之差为所述反射层的厚度； 这样能够保证设置有绝缘层的蓝相液晶面板为单盒厚， 即在反射区和透射区 的蓝相液晶层厚度一致。
需要注意的是， 所有附图均用于参考， 而并非按照实际大小绘制， 因此 图示不应作为反射区和透射区形状或大小的限定。第一像素电极和第二像素 电极的尺寸可以设置为相同， 也可以设置为不同。
上述各电极同层设置是指上述第一像素电极、第二像素电极和公共电极 是由同一透明导电薄膜通过构图工艺形成的。 第一像素电极和第二像素电极 无电连接关系， 且分别由第一数据线和第二数据线施加不同电压， 公共电极 是指和公共电极线连接的电极。
上述在通电情况下， 由第一数据线、 第二数据线分别向第一像素电极、 第二像素电极施加不同电压， 至于施加给两像素电极的电压值的确定与蓝相 液晶的性质（如双折射率性质， 介电各向异性性质， 科尔常数等）相关。 例 如， 可以按照以下测试方法针对包含特定一种蓝相液晶的面板， 确定两电压 值的比例关系。 首先， 按照预先制造测试面板， 该测试面板中填充上述特定 的一种蓝相液晶。其次，通过第一数据线给透射区的第一像素电极施加电压， 通过第二数据线给反射区的第二像素电极施加电压， 分别绘制该测试面板的 透射区和反射区的 V-T (电压-透过率） 曲线特性， 分析两区域的曲线特性， 并且依次得到在各个透过率一致的位置处所对应的第一、第二数据线的电压 值。 在本发明实施例中对上述施加给两像素电极的电压值不加限定， 以能够 使得同一像素区域的透射区、反射区中用于显示的光线通过所述蓝相液晶层 所产生的相位延迟量相同为准； 但位于同一像素区域的第一像素电极和公共 电极间的压差必须大于第二像素电极和公共电极间的压差， 这样才为透射区 和反射区的相位延迟量相同提供了条件。
进一步的， 在一个示例中， 上述蓝相液晶面板还可以包括： 设置在所述 第一基板 11外侧的第一四分之一波片 23、 第一二分之一波片 22、 以及第一 偏振片 21 ; 设置在所述第二基板 12外侧的第二四分之一波片 24、 第二二分 之一波片 25、 以及第二偏振片 26。
在该示例中， 例如在所述第一基板 11 的外侧， 从内至外依次设置有第 一四分之一波片 23、 第一二分之一波片 22、 以及第一偏振片 21 ; 在所述第 二基板 12的外侧， 从内至外依次设置有第二四分之一波片 24、 第二二分之 一波片 25、 以及第二偏振片 26。
下面， 以上述 IPS型显示器中的蓝相液晶面板如何实现半透半反显示为 例进行详述。
图 4为蓝相液晶面板在不加电时的结构示意图。 由于不加电压时， 蓝相 液晶层中的蓝相液晶分子是各向同性的， 而透射区、 反射区中用于显示的光 线经过各向同性的蓝相液晶层不会产生相位延迟量。 若第一偏振片 21和第 二偏振片 26的偏振方向呈 90度夹角， 出射光线会被第二偏振片完全挡住， 从而实现暗态的显示。
图 5为蓝相液晶面板在加电时的结构示意图。蓝相液晶分子在水平电场 作用下， 产生水平方向的相位延迟。 通过向第一像素电极、 第二像素电极施 加不同电压，使得位于同一像素区域的第一像素电极和公共电极间的压差大 于第二像素电极和公共电极间的压差。 由于压差越大所产生的电场就越强， 故而透射区将产生较强的电场强度，蓝相液晶分子在较强的电场作用下会产 生较大的相位延迟 Δ ηΐ , 而反射区将产生较弱的电场强度， 蓝相液晶分子在 较弱的电场作用下会产生较小的相位延迟 Δ η2。 由于反射区的光线会两次通 过蓝相液晶层， 所以反射区的光线经过蓝相液晶层的传播距离 D2约为透射 区的光线经过蓝相液晶层的传播距离 Dl的 2倍， 即大概 D2=2*D1。 于是， 可以通过给第一像素电极和第二像素电极施加不同电压， 能够使得同一个像 素区域的透射区、反射区中用于显示的光线通过所述蓝相液晶层所产生的相 位延迟量相同， 即为 Δ ηΐ *Dl= A n2*D2, 以达到半透半反的显示效果。 如果 位于透射区的相邻条状电极的间距 dl 与位于反射区的相邻条状电极的间距 d2相同， 且 dl=d2, 则可无需考虑透射区和反射区的相邻条状电极的间距对 所产生的水平电场的影响， 而是利用了施加给位于透射区的第一像素电极和 施加给位于反射区的第二像素电极的不同电压对电场的影响。
针对上述 ADS型显示器中的蓝相液晶面板如何实现半透半反显示可以 参考上述原理， 在此不加赘述。
本发明实施例提供的透反式蓝相液晶面板为单盒厚，在通电时位于同一 像素区域的第一像素电极和公共电极间的压差大于第二像素电极和公共电 极间的压差， 使得透射区、 反射区中用于显示的光线通过所述蓝相液晶层所 产生的相位延迟量相同， 从而实现单盒厚透反式蓝相液晶面板的显示功能。 由于本发明实施例中釆用的是单盒厚的结构， 故可简化制作工艺的难度。 例 如，优选地可将位于透射区的相邻条状电极的间距等于反射区的相邻条状电 极的间距。
需要说明的是， 为清楚地描述本发明所要保护的结构， 故与本发明不相 关的结构在各实施例及附图中做简化或省略处理， 并且在各实施例及附图中 做简化或省略处理的结构都是本领域技术人员在没有作出创造性劳动前提 下容易得到的， 故在本实施例不加赘述。
另外， 需要注意的是， 本发明实施例提供的上述两种蓝相液晶面板属于 一个总的发明构思， 该总的发明构思为： 在通电情况下， 使同一像素区域的 透射区产生较强的电场强度， 而反射区产生较弱的电场强度， 从而在透射区 的蓝相液晶分子产生较大的相位延迟，在反射区的蓝相液晶分子产生较小的 相位延迟， 进而使得同一个像素区域的透射区、 反射区中用于显示的光线通 过所述蓝相液晶层所产生的相位延迟量相同。影响电场强度的因素主要有两 个： 一是相邻条状电极的间距， 二是像素电极和公共电极的压差。 图 1、 2、 图 7、 图 8所示的蓝相液晶面板， 在一个像素区域内只有一个像素电极， 故 而透射区和反射区内两电极间的压差是相同的， 在此前提下， 通过在透射区 和反射区设置位于同一层且不同的相邻条状电极的间距， 以产生不同的电场 强度。 图 4、 5、 图 10、 图 12所示的蓝相液晶面板， 例如在透射区和反射区 设置位于同一层且相同的相邻条状电极的间距， 在此前提下， 通过向第一像 素电极和第二像素电极施加不同电压， 使得透射区和反射区内的两电极（像 素电极和公共电极） 间的压差不同， 以产生不同的电场强度。
本实施例还提供一种显示装置， 其包括上述任一种蓝相液晶面板， 所述 显示装置可以为液晶显示器、 液晶电视、 数码相框、 手机、 平板电脑等具有 任何显示功能的产品或者部件。
以上所述仅是本发明的示范性实施方式， 而非用于限制本发明的保护范 围， 本发明的保护范围由所附的权利要求确定。
