下面结合附图和实施例对本申请作说明。
参考图2，本申请实施例公布了一种显示面板包括：
基板60；
光学膜片43，贴附于基板60的外表面；以及
标记50，设置在基板60上，位于光学膜片43的边缘对应预设的合格范围。
光学膜片43与基板贴合对位，标记50设在基板上且在光学膜片43边缘对应位移合格范围，在机器或者人工贴合后，可以快速判断和读取光学膜片43贴附是否合格以及估量误差，方便后期质检时也可以提高质检的速度，直接观察分辨，提高可操控性。当然，如果生产环节采用对位显示装置，也可以通过识别标示进行光学膜片43的对位贴附，通用性好且贴附精度高。
本申请的技术方案适用于各种类型的显示面板，如薄膜晶体管液晶显示器(Thin Film Transistor-Liquid Crystal Display，TFT-LCD)，机发光二极管(Organic Light-Emitting Diode，OLED)、等离子等显示面板；适用于光学膜片43、扩散片、掩膜片等类型膜片。
以下实施方式如无特殊说明，显示面板以薄膜晶体管液晶显示器(Thin Film Transistor-Liquid Crystal Display，TFT-LCD)为例，光学膜片贴附偏光片为例。
以下分别基于第一基板和第二基板举例阐述本申请构思。
参考图2，在一实施例中，第一子标记51、第二子标记52和第三子标记53形状为长条形，第一子标记51和第三子标记53的长度大于第二子标记52的长度。
如果长度一样，品控看久了会产生视觉疲劳，不容易区分对应的标记50属于哪种标记50，增大人工误判的风险。品控最重要的是识别不良品，因此重点需要关注的是偏光片是否偏离第一子标记51，第三子标记53，因此需要把第二子标记52适当做短，让品控能重点关注第一子标记51和第三子标记53，提高判断的准确性。
参考图2，在一实施例中，标记50包括多个第四子标记54和第五子标记55，每个第四 子标记54等距离设于第一子标记51和第二子标记52之间，每个第五子标记53等距离设于第二子标记52和第三子标记53之间，第四子标记54和第五子标记55的长度相同，第四子标记、第五子标记的长度小于第一子标记的长度，第四子标记和第五子标记的长度等于第二子标记的长度，相邻两个第四子标记54之间的间距相等，相邻两个第五子标记55之间的间距相等，相邻两个第四子标记54之间的间距等于相邻两个第五子标记55之间的间距。
作为刻度尺，子标记之间等间距，子标记越多，位移精度就越高，子标记形成一个刻度尺，偏光片40贴附时，刻度标记越细致，贴附的位移误差越小，因为第四子标记54的参考点多，选择第二子标记52和靠近第二子标记52的第四子标记54作为参照，虽然在子标记正向和负向贴附的边界里都可以，但是工艺求精，生产中，也可引导偏光片40贴附的离中心预设位置更近，使贴附校准率度更高。
参考图3，在一实施例中，第一偏光片41设置在第一基板10的第一表面12，第一表面为第一基板10远离液晶层30的那一面；
标记50形成于第一基板10的第二表面13，第二表面13靠近液晶层30。
在第一基板10与第一偏光片41对位贴合时，标记设于第一基板10的第二表面，节省了工序，如果在偏光片贴附的那面做此标记会重新启用其他工序制得此标记，在后期质检时，从正反两面都可以判断，提供判断渠道的多样性。
标记50也可形成于第二基板20，具体实施方式参照第一基板10。
在一实施例中，标记50采用与第一基板10的黑矩阵相同材料制成。
在制程第一基板10的同时，采用与第一基板10的黑矩阵相同材料，同一制程黑矩阵时，直接顺带制程标记，无需其他制程，制程简单，黑矩阵为黑色，相对其他颜色，作为标记显示明显，辨识度更高。
在一实施例中，标记50采用与第二基板20的金属层相同的材料制成。
第二基板形成主动开关阵列，扫描线、数据线、共通线等都属于金属层包括的范围内，在制程阵列基板的同时，采用与第二基板20的金属层相同材料，可以在制作第二基板20各金属层的时候，同步形成标记，无需其他制程，制程简单。
参考图5，在一实施例中，标记50包括：
第一子标记51，对应偏光片40贴附正向边界位置，正向边界位置对应光学膜片在正向方向上偏移合格的最大容忍位置；
第二子标记52，对应偏光片40贴附中心位置设置，中心位置对应光学膜片预设合格的最佳位置；
第三子标记53，对应偏光片40贴附负向边界位置，负向边界位置对应光学膜片在负向方向上偏移的合格最大容忍位置；
正向方向为靠近基板边缘所在的方向，负向方向为远离基板边缘的方向，中心位置和最佳位置为误差为0的位置，最大容忍位置为合格的边界所在位置，超过这个容忍位置就不合格，光学膜片边缘设于正向边界位置和负向边界位置之内为合格，反之，设于正向边界位置和负向边界位置之外则为不合格。
当偏光片贴附在玻璃上，需要比玻璃的尺寸小，偏光片的边缘离玻璃的边缘有一定的距离。这个距离的大小关系到后续制程和组成模组的外框的压扣。如果这个距离太小有些压头就会压到偏光片上；这个距离如果太大，外框就会压扣不上偏光片，导致外框压扣不牢，所以就界定了一个合格范围，因此从品控人员来讲，最关心的就是目标产品是否合格，最简单的方式就是用三条子标记判别，第一子标记51为正向的合格线，第三子标记53为负向的合格线，第二子标记为误差为0的最佳位置，超越此范围直接判定不合格，同时也保证前期偏光片贴附在玻璃上的良率。
参考图5，在一实施例中，第一子标记51、第二子标记52和第三子标记53形状为长条形。
由于偏光片40一般为矩形，边缘是直线段，因此用长条形好对位，可以跟边缘完全重合，长条形的子标记，易对位。
参考图5，在一实施例中，第一子标记51、第二子标记52、第三子标记53平行，三条子标记长度相等。
在进行偏光片40贴附时对子标记50进行对位时，因为是平行对位，偏光片40为矩形，与标记50对位肯定平行贴附对位，所以贴附时会有整体位移偏离，易参考，便于判定位移的大小是否在合格与不合格的判定范围之间。
参考图8，在一实施例中，标记50包括四组标记50，一组标记50包括两个标记50，基板60对应光学膜片43的四个角的位置处，都分别设置一组标记50。
偏光片40和基板对应四个角贴附，四边角都设有标记50，方便质检人员判别倾斜的角度和位移的距离，每组的两个标记位于对应偏光片角的两边，这样横向和纵向限制位移方向都有，四个边角对应设置四组，这样位移偏离的距离和倾斜角度误差就更小，位移贴附和角度贴附的精度相对只在一个边设标记50时贴附的精度大大提高，无论质检人员站在哪一侧，任何视角都可以直观判定合格与不合格，可控性更高。
参考图6，在一实施例中，第一子标记51、第二子标记52和第三子标记53一端重合于一点，形成重合点，另一端呈扇形分布。
一端重合于一点，另一端呈扇形分布，明显形成夹角，易于倾斜角度的检测。
参考图6，在一实施例中，标记50包括第六子标记56，第六子标记56为圆形；
重合点为第六子标记56的圆心且长度相等；另一端点分别落在圆周上。
首先圆的面积大，易捕捉，易对位，使偏光片的边角很快捕捉到第一基板的边角，第一子标记51，第二子标记52，第三子标记53，重合点为第六子标记56的圆心；形成一定的夹角，可以识别偏光片40的倾斜角度，另一端点分别落在圆周上，通过圆周的射线会给视线造成混乱，避免质检人员判别错误，另一端落在圆周上，易于清晰检查角度。
在一实施例中，标记50为镂空结构。
要形成镂空的标记50，必然要在标记50周围形成不透光的区域，以增加对比度。特别标记所在的区域还有其他结构部件，容易跟标记50混淆的时候，采用镂空的标记更易识别。
在一实施例中，标记为实心结构。
实心目标大，比虚线表达更为浓重，显眼，易识别，增大目标的显眼度，可以提高贴附效率和精度。
参考图5，在一实施例中，第一子标记51、第二子标记52和第三子标记53形状是三角形。
因为三角有尖角，尖角与偏光片边缘易对位贴附，尖角就像是一个指针，于偏光片边缘对齐，清楚的可以眼部识别，贴附对位是否准确，也便于质检人员直接读取结果。
在一实施例中，第一子标记51、第二子标记52和第三子标记53形状是圆形。
因为圆形范围均匀，圆的范围大，目标大，易识别对位，标记40大，不用刻意寻找，不管是对安装个基板之间还是对后期质检都可以提高效率。
参考图6，在一实施例中，标记50还包括多个第七子标记57分别对应第一子标记51、第二子标记52和第三子标记53的位置设置；第七子标记57显示对应第一子标记51、第二子标记52和第三子标记53的角度值信息。
以工厂规格为2°时为例，正向贴附合格边界对应第七子标记57字母值2°，负向贴附合格边界对应第七子标记57的字母值-2°,预设贴附合格的中心位置对应0°，在范围角度值里为合格。
参考图2，在一实施例中，标记50还包括多个第八子标记58分别对应第一子标记51、第二子标记52和第三子标记53的位置设置；第八子标记58显示对应第一子标记51、第二子标记5和第三子标记53的刻度值信息。
以工厂规格为500μm时为例，正向贴附合格边界最大值对应第八子标记58刻度值为500μm，负向贴附合格边界最大值对应第八子标记58的刻度值-500为μm，预设贴附合格的中心位置对应刻度值为0，方便质检人员可以判定位移偏离的距离。
参考图5，在一实施例中，标记50还包括多个第九子标记59分别对应第一子标记51、第二子标记52和第三子标记53的位置设置；第九子标记59显示对应第一子标记51、第二子标记52和第三子标记53的字母值信息。
以工厂规格为A和B时为例，正向贴附合格边界对应第九子标记59字母值为A，负向贴附合格边界对应第九子标记59的字母值为B,预设贴附合格的中心值对应的字母值为0，不管是有没有技术功底的质检员都可以看懂，简单易操作。
作为本申请的另一实施例，参考图1至图5所示，公开了一种显示面板包括：
基板60；
偏光片40，贴附于基板60的外表面；
标记50，设置在基板60上，位于偏光片40的边缘对应预设的合格范围。
基板60包括：
第一基板10；
第二基板20，与第一基板10平行相向设置，形成主动开关阵列；
第一基板10包括第一表面12和第二表面13；
第一偏光片41设置在第一基板10的第一表面12，第一表面为第一基板10远离液晶层30的那一面；
标记50形成于第一基板10的第二表面13，第二表面13和第四表面23靠近液晶层30；
标记也可形成第二基板20，具体特征参考第一基板；
标记50包括：
第一子标记51，对应偏光片40贴附正向边界位置，正向边界位置对应光学膜片在正向方向上偏移的合格范围；
第二子标记52，对应偏光片40贴附中心位置设置，中心位置对应光学膜片预设合格的最佳位置；
第三子标记53，对应偏光片40贴附负向边界位置，负向边界位置对应光学膜片在负向方向上偏移的合格最大容忍位置；
第一子标记51、第二子标记52、第三子标记53平行，三条子标记长度相等设置；
偏光片40临接的边缘包括第一边缘和第二边缘，第一边缘与第二边缘垂直；
标记50每两个为一组，包括第一标记50和第二标记50；
第一标记50包括长条形的第一子标记51、第二子标记52、第三子标记53；第一标记50的第一子标记51、第二子标记52、第三子标记53在第一方向上相互平行，第一方向与偏光片40的第一边缘平行；
第二标记50包括长条形的第一子标记51，第二子标记52，第三子标记53；第二标记50的第一子标记51、第二子标记52、第三子标记53在第二方向上相互平行，第二方向与偏光片40的第二边缘平行，第一方向与第二方向垂直；
标记50包括四组标记50，基板60对应光学膜片43的四个角的位置处，都分别设置一 组标记50；
第一子标记51，第二子标记52，第三子标记53形状为长条形，第一子标记51和第三子标记53的长度大于第二子标记52的长度；
标记50包括多个第四子标记54和第五子标记55，每个第四子标记54等距离设于第一子标记51和第二子标记52之间，每个第五子标记53等距离设于第二子标记52和第三子标记53之间，第四子标记54和第五子标记55的长度一致，第四子标记54、第五子标记55的长度小于第一子标记51的长度，第四子标记54和第五子标记55的长度等于第二子标记的长度，相邻两个第四子标记54之间的间距相等，相邻两个第五子标记55之间的间距相等，相邻两个第四子标记54之间的间距等于相邻两个第五子标记55之间的间距；
标记50还包括多个第八子标记58分别对应第一子标记51、第二子标记52、第三子标记53的位置设置；第八子标记58显示对应第一子标记51、第二子标记52、第三子标记53的刻度值信息。
标记形成一个刻度尺，从品控人员来讲，最关心的就是目标产品是否合格，所以最简单的方式就是用三条子标记判别线段位移是否在合格的范围内，生产中也可通过此标记对位进行贴附，提高贴附精度，增加良率，标记50有两组设于对应偏光片40角两侧，分别对应四个角，各个角度视角都可以直观判别，标记制作在第二表面相对比第一表面节省工序，同理第二基板21也是节省工序，在后期质检时，从正反两面都可以判断，提供判断渠道的多样性，第一子标记51为正向合格边界，超过边界为不合格，第三子标记53为负向合格边界，超过为不合格，中心位置为预设最佳位置，提高效率，品控人员出现疲劳时，三条等长易出错，因此需要把第二子标记52适当做短，第四子标记54和第五子标记55同时做短，参差不齐，减少品控人员疲劳时的出错率，正向方向为靠近基板边缘所在的方向，负向方向为远离基板边缘的方向，中心位置和最佳位置为误差为0的位置，最大容忍位置为合格的边界所在位置，超过这个容忍位置就不合格，光学膜片边缘设于正向边界位置和负向边界位置之内为合格，反之，设于正向边界位置和负向边界位置之外则为不合格，参照2图，箭头垂直指向基板边缘为正向方向，箭头垂直指向远离基板边缘的方向为反向方向，正向边界位置与负向边界位置对应刻度值与角度值参数设置，这个边界就是合格与不合格的分界线。
以工厂规格为500μm时为例，则正向边界合格的最大值对应第八子标记58刻度值为500μm，负向边界合格最大值对应第八子标记58的刻度值-500为μm，中心位置对应刻度值为0，，由于偏光片40一般为矩形，边缘是直线段，因此用长条形好对位，可以跟边缘完全重合，四个长条的子标记，易对位，子标记越多，精度就越高，刻度尺的子标记越细致，贴附的角度误差越小，虽然在子标记正向和负向贴附的边界里都可以，四个角都设有标记，工艺求精，各个角度判断是否合格的精准率，提高可控性。
作为本申请的另一实施例，参考图1至图5所示，本实施方式与上一实施方式的区别是：
标记50采用与第一基板10的黑矩阵相同材料制成；

作为本申请的另一实施例，参考图6至图7所示，本实施方式与上一实施方式的区别是：
