本发明实施例提供一种液晶显示面板及显示装置。以下将分别进行详细说明。
参阅图3至图8B，并结合图1和图2，图3是本发明的液晶显示面板的结构俯视图。图4是图3所示D区域的挡墙的局部放大示意图。图5是本发明的液晶显示面板的一种结构示意图。图6是本发明的液晶显示面板的另一种结构示意图。图7A和图7B是本发明的挡墙为单层的一种结构示意图。图8A和图8B是本发明的挡墙为多层的一种结构示意图。
本发明提供了一种液晶显示面板100，其包括阵列基板101、彩膜基板102、设置于所述阵列基板101和所述彩膜基板102之间的液晶103，以及位于所述液晶外围非显示区内且对接连接所述阵列基板101和所述彩膜基板102的封框胶（图中未示）。由于此处所指的阵列基板、彩膜基板及液晶的结构与现有技术的阵列基板、彩膜基板及液晶相同，因此，采用相同的标号，参考图1所示。所述液晶显示面板100包括多个像素单元105。
所述液晶显示面板100还包括：至少一层挡墙310，所述挡墙310用于防止涂布于所述彩膜基板102或阵列基板101且呈液态的涂布膜层104由显示区A朝非显示区B扩散，其中所述非显示区B位于所述显示区A的外围。
在本实施例中，所述至少一层挡墙310设置于所述封框胶内。也就是说，连接彩膜基板102和阵列基板101的封框胶中具有挡墙310，而挡墙310能够防止液晶103对挡墙310外侧的封框胶进行穿刺。另外，所述挡墙310还可以防止由于液晶103穿刺封框胶而使空气进入液晶盒导致的气泡不良，增加产品的良率和信赖性，提高产品质量。
另外，本发明提供的液晶显示面板100中，阵列基板101与彩膜基板102之间可以通过挡墙310起到支撑盒厚的作用，从而不需要向封框胶中添加硅球、玻璃纤维等支撑物，达到简化原有生产工艺及节省制造成本的目的。
进一步，为了增强挡墙310位置关系的稳定性，以及增强封框胶与彩膜基板102或阵列基板101之间粘接的稳定性，优选地，所述挡墙310可以与彩膜基板102或阵列基板101上的任一结构同步形成。当挡墙310为多层时，多层挡墙310中可以有一部分与阵列基板101的任一结构同步形成，一部分与彩膜基板102的任一结构同步形成。
彩膜基板上102的结构包括但不限于玻璃基板、间隔柱107、黑矩阵层106、红色树脂层、绿色树脂层、蓝色树脂层。阵列基板101上的结构包括但不限于玻璃基板、栅极绝缘层、栅极、钝化层、像素电极层。具体地，以彩膜基板102上的红色树脂层、绿色树脂层、蓝色树脂层为例，所述挡墙310采用与红色树脂层、绿色树脂层、蓝色树脂层（即色阻层，图中未示）相同的材料，在通过涂胶、曝光、显影等工艺形成红色树脂层、绿色树脂层、蓝色树脂层图案的同时，在封框胶对应区域内同步形成所述挡墙310的图案。再如，以阵列基板101上的栅极层（图中未示）为例，所述挡墙310采用与栅极层相同的材料，在通过涂胶、曝光、显影等工艺形成栅极层图案的同时，在封框胶对应区域内同步形成所述挡墙310的图案。需说明的是，为了保证所述挡墙310的阻挡效果，所述挡墙310需要有一定的高度。当所述挡墙310采用与色阻层或间隔柱107相同的材料或者非金属材料时，所述挡墙310的宽度需要大于25微米。由于所述挡墙310采用与色阻垫块（或色阻层）、间隔柱或金属垫块（或金属层）相同的材料，因此，所述挡墙310可以和显示区A中的上述结构同时形成，从而不增加额外工序。另外，所述挡墙310与彩膜基板102或阵列基板101上的任一结构同步形成，这样进一步增强封框胶与彩膜基板102或阵列基板101之间的粘接强度。
在一实施例中，所述挡墙310整体为一封闭的四边形，如图3所示，与存在于外围非显示区B的封框胶具有相同的位置分布，此封闭四边形将显示区A外围边缘区域全部挡住，防止液晶103对封框胶的穿刺。
所述挡墙310自身可以为板状结构，或者为多个圆柱状结构（例如椭圆状）紧密排列而成，如图7A和图7B所示。当所述挡墙310自身为圆柱状结构时，圆柱状结构的外表面为弧形，可以增大挡墙310与封框胶之间的接触面积，进而增大封框胶与挡墙310之间的粘接面积，进一步增强封框胶与挡墙310之间粘接的稳定性。
所述挡墙310可以为单层或多层。当所述挡墙310为多层时，如图8A和图8B所示，相邻两层的挡墙310之间具有用于填充所述封框胶的空隙。在此，相邻两层的所述挡墙310之间的距离D2可以设置为介于300微米至600微米之间，如图4所示.
优选地，当所述挡墙310为多层时，可以如此设计，每一层挡墙310包括多个间隔分布的挡块311，且相邻两层挡墙310中，一层挡墙310中相邻两个挡块311之间的间隙被另一层挡墙310中的一挡块311遮挡。这样能够有效地防止呈液态的涂布膜层104回流而引起显示区A外围边缘偏厚的情况。
另外，所述挡墙310在所述彩膜基板102或所述阵列基板101所在平面的正投影中靠近所述显示区A一侧的边缘与所述显示区边缘的距离D1介于100微米至200微米，如图4所示。
根据本发明的另一方面，本发明提供一种显示装置200，如图9所示，所述显示装置200包括上述液晶显示面板100。所述显示装置可以为液晶电视、液晶显示装置、手机、数码相框、平板电脑等任何具有显示功能的产品或部件。
本发明的优点在于，本发明所述液晶显示面板及显示装置能够有效地防止由显示区向其外围边缘流平扩散的问题，从而避免涂布膜层在显示区外围边缘出现厚度不均匀的现象，进一步防止涂布膜层厚度不均导致显示过程中出现显示不良的问题，有利于提高显示效果。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
本申请的主题可以在工业中制造和使用，具备工业实用性。
