在一个实施例中，上述第二保护层3的厚度大于上述偏光基体1的厚度。这样，通过将上述第二保护层3的厚度设置为大于上述偏光基体1的厚度，从而该第二保护层可3对上述偏光基体1实现较好的支撑和保护。当然，在本实施例中，根据实际情况和具体需求，上述第二保护层3的厚度也可等于或小于上述偏光基体1的厚度，此处不作唯一限定。
在一个实施例中，请参阅图3，在本申请中上述偏光片上还设有一层分离膜5，该分离膜5设置于上述柔性胶层4背对上述偏光基体1的一面上，通过设置一层分离膜5，从而可保护柔性胶层4避免遭到外部环境的污染。在本实施例中，上述分离膜5粘结于柔性胶层4上，当然，在本实施例中，上述分离膜5也可呈其他方式设置于上述柔性胶层4上，此处不作唯一限定。
在本实施例中，当需要使用柔性胶层4时，此时，可通过撕下分离膜5，从而将柔性胶层4黏贴于上述显示基板上，进而将整个偏光片安装于上述显示基板上，当需要更换偏光片时，此时可通过光照去除柔性胶层4，实现偏光片与上述显示基板的分离。
在一个实施例中，上述分离膜5的厚度小于柔性胶层的4厚度，一方面可 保护柔性胶层4避免遭到外部环境的污染，另一方面也防止分离膜5厚度太大，增大制作的成本，当然，在本实施例中，根据实际情况和具体需求，上述分离膜5也可设置为等于上述柔性胶层4的厚度，此处不作唯一限定。
在一个实施例中，请参阅图4，在本申请中上述偏光片上还设有保护膜6，该保护膜6设置于上述第一保护层3上，可选地，上述保护膜6设于上述第一保护层3背对上述偏光基体1的一面上。这样，通过设置一层保护膜6，进一步的保护上述偏光基体1，避免该偏光基体1受到外部环境的污染。可选地，该保护膜6粘结于上述第一保护层2上，当然，也可通过其他方式设置于该第一保护层2上，此处不作唯一限定。
在一个实施例中，上述保护膜6的厚度小于上述第一保护层2的厚度，这样，一方面可保护第一保护层2免受污染，另一方面可使得偏光片变得较为薄型化。当然，在本实施例中，上述保护膜6的厚度也可设置为大于或等于上述第一保护层2的厚度，此处不作唯一限定。
在一个实施例中，上述保护膜6粘结于上述第一保护层2上，这样，通过该种方式，可快速的将上述保护膜6安装于上述第一保护层2上，当保护膜6受损时，也可便于拆卸更换上述保护膜6，当然，在本实施例中，上述保护膜6也可通过其他方式安装于上述第一保护层2上，此处不作唯一限定。
在另一个实施例中，提供一种偏光片，包括偏光基体1，在该偏光基体1的上下两面分别设置有第一保护层2与第二保护层3，该第一保护层2与第二保护层3分别对称设置于上述偏光基体1上，在上述第二保护层3上设有柔性胶层4，该柔性胶层4黏贴于显示基板7，且该柔性胶层4为紫外光解黏性胶制作的薄膜层。这样，通过在第二保护层3与显示基板之间设置柔性胶层4，且上述柔性胶层的厚度为1.5毫米。这样，一方面可通过柔性胶层4将上述第 二保护层黏贴于上述显示基板上，另一方面，当需要将上述第二保护层3与上述显示基板实现分离时，此时可通过进行光照，该柔性胶层4在光照的照射下发生交联反应而被去除，实现第二保护层3与上述显示基板的快速分离，进而实现偏光片与显示基板的快速分离，避免了因偏光片在替换过程中导致产品报废的问题发生，降低了成本，通过设置第一保护层2与第二保护层3，从而可增强偏光基体1的机械性能，使得该偏光片具有一定的强韧性，此外，通过将上述柔性胶层4设置为UV解黏性胶层，从而可通过UV光照使得柔性胶层4发生交联反应而容易被去除，且通过使用UV光照也不会影响偏光基体1内的晶体结构，保证了偏光基体1的使用性能不受影响。
在一个实施例中，上述柔性胶层4通过粘结、热压、印刷等方式覆盖于上述第二保护层3上，通过使用上述方式从而可较好的实现将柔性胶层4贴附于第二保护层3上，当然，此处也可通过其他方式设置，此处不作唯一限定。
在本实施例中，还提供一种显示装置，该显示装置包括显示主机9和底座8，该底座8可用于支撑上述显示主机9，具体地，上述显示主机9包括显示基板7，在该显示基板7上设置有偏光片，该偏光片为如上所述的偏光片，此处不作赘述。
在本实施例中，通过设置UV解黏性胶制作的柔性胶层4，这样，在保证偏光基体1使用性能的前提下，通过UV光照使得柔性胶层4发生交联反应而容易被去除，进而实现偏光片与显示基板7的快速分离，避免了因偏光片在替换过程中导致产品报废的问题发生，降低了生产成本。
以上仅为本申请的可选实施例而已，并不用于限制本申请。对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
