其中，所述偏光器件还包括粘胶层和离型膜，所述粘胶层设置在所述第一支撑层和所述离型膜之间
其中，所述液晶盒的入射光一侧还设置有下偏光片。
为解决上述技术问题，本发明采用的又一个技术方案是：提供一种偏光器件的制造方法，包括：制得一第一支撑层；在所述第一支撑层上粘贴一用于输出线偏振光的偏光层；在所述偏光层上粘贴一具有m/4波长相位延迟的转换层，所述m为大于0的奇数，所述转换层的光轴与所述偏光层的偏光轴之间的夹角θ为n*90°+45°，其中n为不小于0的整数。
其中，所述转换层为经过45°奇数倍斜延伸的三醋酸纤维素层、环烯烃聚合物层、聚对苯二甲酸乙二醇酯层、聚碳酸酯层或聚甲基丙烯酸甲酯层。
本发明的有益效果是：区别于现有技术的情况，本发明提供一种使用转换层的偏光器件，因转换层的光轴与偏光器件中偏光层的偏光轴之间的夹角θ为n*90°+45°，其中n为不小于0的整数，m为大于0并且小于90度的角度，因此能使经过偏光器件的线偏振光转化为圆偏振或椭圆偏振光。通过这种方式，无需在现有的偏光片之外再设置类似作用的圆偏振实现材料，即能利用偏光器件本身低成本地改变液晶显示装置的出射光偏振状态，使其成为圆偏振或椭圆偏振光，从而达到保护人眼的效果、结构简单；同时，本发明实施例不需要在偏光器件之外额外增加类似作用的圆偏振实现材料，因此使用本发明偏光器件的液晶显示产品保持轻薄结构，并且无需在偏光器件之外设置额外增加类似作用的圆偏振实现材料而导致的复杂工艺，降低成本。

【具体实施方式】
偏光片是一种经多层膜贴合制成的光学功能器件。请参阅图1，偏光片的基本结构包括：
最中间的偏光层14，例如聚乙烯醇（PVA）层，偏光层14具有偏振作用；内外两层支撑层15、13，通常内外两层支撑层15、13可以根据需要选用三醋酸纤维素（TAC）、环烯烃聚合物（COP）、聚对苯二甲酸乙二醇酯（PET）、聚碳酸酯（PC）、聚甲基丙烯酸甲酯（PMMA）等材料；粘胶层（PSA film）16，粘胶层16用于贴合液晶盒和偏光片；离型膜 (Release film) 17，离型膜17是为了对粘胶层16进行保护，贴合液晶盒时可以揭下；为使偏光片具有防止放射、眩光及增加其硬度等功能，通常会在第二支撑层13上面进行表面处理以形成一外表面处理层（AG/AR layer）12；为保护偏光片，还可以在表面处理层12上设置一保护膜11，该保护膜11可以在组装模组时揭下。
液晶装置中使用到偏光片时，通常成套使用，即液晶盒的上表面的上偏光片和液晶盒的下表面的下偏光片。
本发明基于将偏光层输出的线偏振光转化为圆偏振或椭圆偏振光的目的，提供一种偏光器件。
请参阅图2，图2为本发明的偏光器件一个实施方式的结构示意图，本实施方式的偏光器件包括第一支撑层21、用于输出线偏振光的偏光层22以及具有m/4波长相位延迟的转换层23，m为大于0的奇数。其中，第一支撑层21、偏光层22以及转换层23依次层叠，转换层23的光轴与偏光层22的偏光轴之间的夹角θ为n*90°+45°，其中n为不小于0的整数。比如，转换层23的光轴与偏光层22的偏光轴之间的夹角为45°或135°。
其中，第一支撑层21、偏光层22以及转换层23依次叠置，转换层23同时作为第二支撑层，以配合第一支撑层21实现支撑偏光层22的作用。这样，通过一个转换层23既可以将偏光层22输出的偏振光转换为圆偏振或椭圆偏振光，又可以实现支撑功能，节约偏光器件的制造成本。
其中，转换层23的材料为具有m/4波长相位延迟的材料。m为大于0的奇数。比如1、3、5等等。转换层23的材料可以是三醋酸纤维素(TAC)、环烯烃聚合物(COP)、聚对苯二甲酸乙二醇酯(PET)、聚碳酸酯（PC）或聚甲基丙烯酸甲酯(PMMA)中的任何一种材料。其中，较优选用TAC作为转换层23的材料，因为其波长分散比更接近理想圆偏振片，可以得到更接近圆偏振光状态的出射光线。第一支撑层21和现有的偏光片中的内支撑层15材料、结构均相同。
图3为不同材料的波长分散比示意图，由图可知，利用TAC作为转换层23的材料可以得到更接近圆偏振光状态的出射光线。
其中，偏光层22的材料为聚乙烯醇。通过上述实施方式的阐述，可以理解，本发明提供一种使用转换层的偏光器件，因转换层的光轴与偏光器件中偏光层的偏光轴之间的夹角θ为n*90°+45°，其中n为不小于0的整数，因此能使经过偏光器件的线偏振光转化为圆偏振或椭圆偏振光。通过这种方式，无需在偏光器件之外再设置类似作用的圆偏振实现材料，即能利用偏光器件本身低成本地改变液晶显示装置的出射光偏振状态，使其成为圆偏振或椭圆偏振光，从而达到保护人眼的效果、结构简单；同时，由于偏光层位于支撑层和转换层之间，因此转换层还能对偏光层起保护作用；又，本实施方式不需要在偏光器件之外额外增加类似作用的圆偏振实现材料，因此使用本发明偏光器件的液晶显示产品保持轻薄结构，并且无需在偏光器件之外增加类似作用的圆偏振实现材料而导致的复杂工艺，降低成本。
请参阅图4，图4是本发明偏光器件另一个实施方式的结构示意图，本实施方式的偏光器件除了包括第一支撑层35、偏光层34以及转换层33以外，还包括用于防眩光和防发射的表面处理层32，表面处理层32和偏光层34分别设置在转换层33的两侧表面。其中，本发明实施方式中第一支撑层35还可以选用经过拉伸后具有液晶光学补偿作用的膜片，以实现对液晶盒的光学补偿，进而改善显示效果。
另外，本实施方式的偏光器件还包括保护膜31，保护膜31和转换层33分别设置在表面处理层32的两侧表面。该保护膜31可以在组装偏光器件时揭下。
请继续参阅图4，为实现偏光器件与液晶盒的贴合，本实施方式偏光器件还包括设置于第一支撑层35的下表面的粘胶层36，并进一步包括一用于对粘胶层36进行保护的离型膜37，粘胶层36具体设置在第一支撑层35和离型膜37之间，该离型膜37可以对粘胶层36进行保护，并且在偏光器件贴合液晶盒时揭下。
以上本发明偏光器件各实施方式，可以是以一转换层替换偏光片中的两支撑层中的其中一个，即省略相应的支撑层；当然，在其他实施方式中，偏光器件可以同时包括转换层和两个支撑层，偏光层和转换层位于该两个支撑层之间。
基于以上提供的偏光器件的实施方式，本发明进一步提供一种液晶显示装置。
请参阅图5，图5所示为本发明液晶显示装置一个实施方式的结构示意图，如图5所示，该液晶显示装置包括液晶盒47以及本发明上述任一实施方式提供的偏光器件48。偏光器件48设置于液晶盒47的出射光一侧，且偏光器件中的转换层相对于偏光层远离液晶盒47(偏光器件的各个结构层图中未显示),本实施方式中偏光器件的各个结构层的位置关系以及各层的功能如上述实施方式的描述,在此不再赘述。
其中，本发明提供的液晶显示装置液晶盒47的入射光一侧还设置有下偏光片。本实施方式中的下偏光片包括：偏光层43、内外两层支撑层44、42，粘胶层45、离型膜46以及保护膜41。与前述实施方式相同，离型膜46是为了对粘胶层45进行保护，贴合液晶盒时可以揭下；该保护膜41可以在组装模组时揭下。
本发明提供的液晶显示装置，其上偏光片为采用一转换层的偏光器件，无需在偏光器件之外再设置类似作用的圆偏振实现材料，即能利用偏光器件本身低成本地改变液晶显示装置的出射光偏振状态，使其成为圆偏振或椭圆偏振光，从而达到保护人眼的效果、结构简单；同时，由于采用的偏光器件的偏光层位于支撑层和转换层之间，因此转换层还能作为另外一个支撑层对偏光层起保护作用，本发明实施方式提供的液晶显示装置能够保持轻薄结构，并且无需在偏光器件之外设置圆偏振实现材料的工艺，降低成本。
请参阅图6，图6为本发明偏光器件的制备方法一个实施方式的流程图，本实施方式偏光器件的制造方法包括：
步骤S101：制得一第一支撑层；
本实施方式选用带补偿性能的材料制得第一支撑层，比如TAC、COP、PET、PMMA、液晶等材料，其中，优选使用TAC材料制得第一支撑层。
步骤S102：在第一支撑层上粘贴一用于输出线偏振光的偏光层；
在第一支撑层上粘贴一偏光层。偏光层是偏光器件的核心层，可以输出线偏振光。本实施方式偏光层由聚乙烯醇薄膜经染色拉伸后制成。
步骤S103：在偏光层上粘贴一具有m/4波长相位延迟的转换层，m为大于0的奇数，使转换层的光轴与偏光层的偏光轴之间的夹角为n*90°+45°，其中n为不小于0的整数；
在偏光层上粘贴一转换层，该转换层用于使偏光层输出的线偏振光转化为圆偏振或椭圆偏振光。同时，本发明实施方式中，该转换层还作为第二支撑层，以配合第一支撑层起支撑作用，以隔离水分和空气，保护偏光层。
当然，上述步骤不严格区分先后顺序，实际应用中，可以根据需要调整制造步骤，只要将各层按照结构构成依次叠置在一起即可。
本发明实施方式中，通过辊轮压合使转换层与偏光层贴合，使转换层的光轴与偏光层的偏光轴之间的夹角θ为n*90°+45°，其中n为不小于0的整数，比如θ为45°或135°。具体可参见图7，图7为偏光层、转换层及第一支撑层贴合的示意图，通过卷对卷制程（Roll-to-Roll Process）来实现偏光层、转换层以及第一支撑层的贴合。中左边为贴合前的示意图，右边为贴合后的示意图。其中，转换层41以及第一支撑层43分别位于偏光层42两侧，转换层41的光轴401与偏光层42的偏光轴402的夹角θ为n*90°+45°，其中θ优选为45°或135°。
本发明实施方式中，转换层的材料为具有m/4光波相位延迟的材料，m为大于0的奇数，比如m为1、3、5等等。比如转换层的材料可以是TAC、COP、PET或PMMA等等。其中，最优选用TAC作为转换层的材料，因为其波长分散比更接近理想圆偏振片，可以得到更接近圆偏振光状态的出射光线。
需要注意的是，在本发明另一实施方式中，本发明的偏光器件的制造方法还包括在第一支撑层下表面设置粘胶层，以用于本发明的偏光器件与液晶盒贴合。
基于以上实施方式，本发明还提供一种液晶显示装置的制造方法，包括上述实施方式制造偏光器件的步骤，以及将制造的偏光器件贴合到液晶盒的出射光一侧表面的步骤。
另外，液晶显示装置的制造方法还包括将下偏光片贴合到液晶盒的入射光一侧表面的步骤。
通过上述实施方式的阐述，本发明提供一种偏光器件液晶显示装置及其制造方法，提供使用转换层的偏光器件，因转换层的光轴与偏光器件中偏光层的偏光轴之间的夹角θ为n*90°+45，其中n为不小于0的整数因此能使经过偏光器件的线偏振光转化为圆偏振或椭圆偏振光。通过这种方式，无需在偏光器件之外再设置类似作用的圆偏振实现材料，即能利用偏光器件本身低成本地改变液晶显示装置的出射光偏振状态，使其成为圆偏振或椭圆偏振光，从而达到保护人眼的效果、结构简单；同时，由于偏光层位于支撑层和转换层之间，因此还能对偏光层起保护作用；又，因不需要在偏光器件之外额外增加类似作用的圆偏振实现材料，因此使用本发明偏光器件的液晶显示产品保持轻薄结构，并且无需在偏光器件之外设置额外增加类似作用的圆偏振实现材料而导致的复杂工艺，降低成本。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
