图1至图5分别为液晶显示面板的结构示意图、彩膜基板的结构示意图(一)、彩膜基板的结构示意图(二)、挡墙的生产示意图(一)和挡墙的生产示意图(二)。
如图2和图3本发明的液晶显示面板包括彩膜基板1，彩膜基板1包括第一玻璃层11，第一玻璃层11的上方设有保护层12，该保护层12由ITO制成，彩膜基板1的显示区的边缘13设有黑色矩阵层14和框胶层15，黑色矩阵层14位于第一玻璃层11和保护层12之间，黑色矩阵层14的长度小于第一玻璃层11的长度，黑色矩阵层14的上表面含有挡墙16，框胶层15设在保护层12的端部的上方。
在本发明中，挡墙16的结构有两种形式，其中第一种的结构具体是，如图2所示，挡墙16为在黑色矩阵层14的上表面开设的凹槽141，凹槽141的深度小于黑色矩阵层14的厚度。
如图3所示，本发明的挡墙16的第二种结构具体是，在黑色矩阵层14的上表面凸设的凸起142。
进一步的，如图1所示，本发明的液晶显示面板还包括阵列基板2，阵列基板2与彩膜基板1相对的区域设置有第二玻璃层21，第二玻璃层21上方设有金属层22，具体的，金属层22为栅极，金属层22的两侧分别设有栅极绝缘层23， 栅极绝缘层23的上方设有能保护金属层22的第一钝化层24，框胶层15覆盖金属层22及一个第一钝化层24，另一个第一钝化层24的上方设有色阻层25，在一具体实施方式中，色阻层25为蓝色色阻层。

在本发明中，凸起142的高度小于彩膜基板1与阵列基板2之间的距离，从而防止凸起142对阵列基板2造成破坏。
本发明的彩膜基板1与阵列基板2对位之前会在彩膜基板1与阵列基板2上分别会涂布PI液17，PI液17涂布偏差，易导致PI液17与框胶层15的重叠(Overlap)，从而导致框胶层15脱落，本发明的挡墙16能够有效阻止PI液17与框胶层15的重叠，从而提高液晶显示面板的质量，提高液晶显示面板的良好率。
如图4和图5所示，本发明还提出一种针对本发明的液晶显示面板的制造方法，该制造方法为，彩膜基板1的上方设有光罩3，光罩3包括第一光罩31、第二光罩32和第三光罩33，第一光罩31与第一玻璃层11的上方设有黑色矩阵层14之外的区域相对设置，第二光罩32与黑色矩阵层14相对设置，第三光罩33与挡墙16的区域相对设置，光9通过光罩3入射到彩膜基板1上，其中，第一光罩31的透光率为0，第二光罩32的透光率大于第三光罩33的透光率或第二光罩32的透光率小于第三光罩33的透光率。
在一具体实施方式中，第二光罩32的透光率为100％及第三光罩33为部分透光，在一具体实施例中，第三光罩33的透光率为50％。
在另一具体实施方式中，第二光罩32部分透光，第三光罩33的透光率为100％，在一具体实施例中，第二光罩32的透光率为50％。当然第三光罩33和第二光罩32的透光率可以设定为其他值，只要不相同即可，在此不做具体限制。
本发明对光罩3有两种实施例，实施例一为：光罩3可使用HTM光罩类型，HTM光罩上不同区域设计不同材料，不同材料对光的吸收量不一样，从而可以实现不同区域的光的透过量不同，显影后可以得到不同膜厚的黑色矩阵层14。因彩膜基板1常用负性光阻，见光后的光阻不会被洗掉，该处的黑色矩阵层将会留下。图4中无黑色矩阵层14的地方在光罩3设计上为不透光，即Tr＝0％(对应图4中的第一光罩31部分)，该区域对应第一玻璃层11上区域黑色矩阵层14 会被显影液洗掉；正常黑色矩阵层14区在光罩3设计上为全透光，即Tr＝100％(对应图4中的第二光罩32部分)，黑色矩阵层14会留在彩膜基板1上；而黑色矩阵层14的凹槽141部分采用在光罩3设计上为部分透光，即Tr＝50％(对应图4中的第三光罩33部分)，该穿透率可以根据实验结果做出调整，这里只是给出一个示例透过率，部分透光则该区域光阻较薄，会被洗掉一部分，从而形成图4中的凹槽141结构。另外可以通过调控黑色矩阵层14膜的涂布厚度及光罩3上半透区的透光率的大小来调控凹槽141的形状位置和深浅，从而达到最佳阻挡PI液17的效果，ITO层采用正面蒸镀，不需要使用光罩3。
实施例为如图5所示，光罩3使用HTM光罩类型。因彩膜基板1常用负性光阻，图5中无黑色矩阵层14的地方在光罩3设计上为不透光，Tr＝0％(对应图5中的第一光罩31部分)，正常黑色矩阵层14区为在光罩3设计上为半透光，Tr＝50％(对应图5中的第二光罩32部分)，该穿透率可以根据实验结果做出调整，这里只是给出一个示例透过率，而黑色矩阵层14的凸起142部分在光罩3设计上采用全透光的设计，Tr＝100％(对应图5中的第三光罩33部分)。同实施例一中可以通过调控黑色矩阵层14膜的涂布厚度及光罩3上的半透区的透光率的大小来调控凸起142的形状位置和深浅，从而达到最佳阻挡PI液的效果，ITO层采用正面蒸镀，不需要使用光罩。
虽然已经参考优选实施例对本发明进行了描述，但在不脱离本发明的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本发明并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
