为了更清楚地说明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单介绍，显而易见地，下面描述中的附图仅仅是发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

 本发明的实施方式
以下各实施例的说明是参考附加的图示，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。在图中，结构相似的单元是用以相同标号表示。
通常液晶显示装置包括壳体、设于壳体内的液晶面板及设于壳体内的背光模组 (Backlight module)。其中，液晶面板的结构主要是由一薄膜晶体管阵列基板(Thin Film Transistor Array Substrate，TFT Array Substrate)、一彩色滤光片基板(Color Filter，CF)、以及配置于两基板间的液晶层(Liquid Crystal Layer)所构成，传统的液晶显示装置制造工艺，将阵列基板和彩膜基板通过对盒贴合在一起，形成液晶显示装置；阵列基板和彩膜基板依靠封框胶黏合在一起，且需要在封框胶中添加感光性间隔子（PS，Photo Spacer），用于支撑液晶面板的盒厚，在基板(阵列基板和/或彩膜基板)上设置光阻挡墙(PS Wall，Photo Spacer Wall)来防止液晶对封框胶进行穿刺。另外，还包括配向膜，配向膜通常由(PI，Polyimide Film)材料构成，其表面形成有取向结构，从而使与其接触的液晶分子发生所需的取向。为了便于像素区域排出气泡，采用岛状掩膜，同时为了节省降低液晶的用量，将液晶盒厚度和间隔子高度进行下修，然而，此变更导致边缘区域的液晶盒厚度偏高，且光阻挡墙上存在聚酰亚胺材料堆积，液晶盒厚度不均匀，点灯时边缘有耳朵漏光。
本发明针对现有的液晶显示面板，能够解决非显示区域聚酰亚胺材料在挡墙上堆积，形成跷跷板效应，进而导致液晶盒厚度不均匀，该区域存在耳朵漏光的技术问题，本实施例能够解决该缺陷。

所述第一基板201与所述第二基板202相对设置，其间设有一液晶层（图中未示出），所述第一基板201和所述第二基板202均包括显示区和非显示区，且所述第一基板面向所述第二基板一侧的表面设置有所述第一配向膜203,、所述第二基板面向所述第一基板一侧的表面设置有所述第二配向膜204；所述框胶205设置在所述第一基板201与所述第二基板202之间，紧密粘合所述第一基板201和所述第二基板202，并形成一封闭空间，所述框胶205围绕在液晶显示面板四周将液晶分子与外界阻隔且框限在所述第一基板201与所述第二基板202之间的封闭空间内。
优选地，所述框胶205可采用亚克力树脂与环氧树脂的混合物为材料制成。所述挡墙206设置在所述第一基板201的非显示区表面，且所述挡墙206位于所述第一配向膜的覆盖范围外，所述挡墙206的另一侧设置于所述框胶205的附近处，即所述挡墙206环绕所述液晶层设置，所述胶框205环绕所述挡墙206设置，有效地将液晶与所述框胶205分隔开来；可替代地，所述挡墙206也可以设置在所述第二基板201的非显示区表面，所述第一基板201的显示区与所述第二基板202的显示区之间设置有若干间隔子208，所述间隔子208为离散或连续排列的柱状结构。
其中，所述第一基板表面还设置有所述黑色矩阵207和R、G、B三原色色阻层（图中未示出），所述黑色矩阵207与R、G、B三原色色组层交替规则排列，所述黑色矩阵207可由树脂材料制成，具有遮光的作用，此时，所述第一配向膜203设置于所述黑色矩阵207的表面，所述间隔子208位于所述第一基板201上或位于所述第一基板201的所述黑色矩阵207上，位于任意两相邻色阻层之间，用于支撑起两基板之间的间隙，并使间隙的各部分高度均匀。
优选地，所述挡墙206和所述间隔子208均为负性光阻材料，可替代地，所述挡墙206可以为正性光阻材料，且所述挡墙206的高度低于所述间隔子208，所述挡墙206的截面为梯形，所述梯形的两侧边与所述第一基板201形成的角度均为锐角，所述第一基板201为彩膜基板，所述第二基板202为阵列基板。

本发明的有益效果为：相较于现有的液晶显示面板，本发明的液晶显示面板通过采用调整挡墙站位或降低挡墙高度的形式，可以防止聚酰亚胺材料在挡墙处堆积；解决了现有的液晶显示面板因采用岛状掩膜，间隔子的绝对高度增大，而液晶盒厚度降低，容易形成跷跷板效应，导致液晶盒厚度不均匀，边缘区域有耳朵漏光的技术问题，提升了液晶显示面板及液晶显示装置的产品品质及良率。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
