所述内层挡墙2呈高低不平设置的方式有多种，可以是所述内层挡墙2呈间断设置，还可以请参阅图1和图2，在本实施例中，所述内层挡墙2的上端设有缺口21，使得所述内层挡墙2呈高低不平设置，这样在所述内层挡墙2的低洼处对配向液的阻挡效果较好，可以有效减缓配向液外扩的趋势。
当部分配向液通过所述内层挡墙2，在所述外层挡墙3的阻挡作用下，会被容置于所述内层挡墙2和所述外层挡墙3之间的区域，具体地，请参阅图1和图2，在本实施例中，所述内层挡墙2和所述外层挡墙3之间形成容置区，所述容置区的局部相较于其他部分呈凹陷设置，以形成防溢凹槽4，通过所述防溢凹槽4的设置，可以相对增加所述容置区的容积。
进一步，当沿所述第一涂布区域11的周向，在所述容置区内形成有多个所述防溢凹槽4时，所述容置区的容积相对较大，且减缓配向液外扩的效果相对较好。
请参阅图1，在本实施例中，所述防溢凹槽4呈与所述内层挡墙2的低洼处对应设置，因为所述内层挡墙2的低洼处对配向液的阻挡效果相对较小，通过所述内层挡墙2的低洼处的配向液的量较多，将所述防溢凹槽4与所述内层挡墙2的低洼处对应设置，可以减小有效减缓通过低洼处的配向液进一步外扩的趋势。
在所述容置区内设置所述防溢凹槽4的方式有多种，可是在所述基板1上开设所述防溢凹槽4，还可以是请参阅图1和图3，在本实施例中，在所述容置区内，所述基板1凸设有多个连接所述内层挡墙2和所述外层挡墙3的间隔块5，所述多个间隔块5呈沿所述第一涂布区域11的周向间隔排布，相邻两个所述间隔块5之间形成所述防溢凹槽4，这样所述防溢凹槽4的形成工艺相对较为简单，所述间隔块5可以是与所述内层挡墙2和所述外层挡墙3一体成型，采用相同的材质制成。
对于所述内层挡墙2和所述外层挡墙的材质的限定，在本实施例中，所述内层挡墙2和所述外层挡墙3均为绝缘材料制成，这样所述内层挡墙2和所述外层挡墙3不会对所述显示面板的阵列基板的电场产生干扰。
在本实施例中，所述封装基板结构为彩膜基板，可以通过在所述基板的侧部设有黑矩阵、色阻层或者间隔物等，以形成所述内层挡墙2和所述外层挡墙3，例如，可以是所述基板1设有黑矩阵，在所述间隔区内且环绕所述第一涂布区域11凸设有所述黑矩阵，以形成所述内层挡墙2或所述外层挡墙3；也可以是所述基板1设有色阻层，在所述间隔区内且环绕所述第一涂布区域11凸设有所述色阻层，以形成所述内层挡墙2或所述外层挡墙3；还可以是所述基板1设有间隔物，在所述间隔区内且环绕所述第一涂布区域11凸设有所述间隔物，以形成所述内层挡墙2或所述外层挡墙3。
在所述第一涂布区域11和所述第二涂布区域12之间设置所述内层挡墙2和所述外层挡墙3，具体地，在本实施例中，所述第一涂布区域11和所述第二涂布区域12之间的间距为a，所述内层挡墙2和所述外层挡墙3之间的间距为b，其中，a-b≤9mm，这样所述内层挡墙2和所述外层挡墙3形成对配向液的双重阻挡的效果较好，且所述内层挡墙2和所述外层挡墙3之间形成的用以容置配向液的区域的容积相对较大。
通常所述第一涂布区域11内设有膜层6（请参阅图2和图3，在本实施例中，所述膜层6包括间隔设置的多个黑矩阵61、以及设于所述多个黑矩阵61之间的红色色阻层62、绿色色阻层63和蓝色色阻层64，当所述膜层6的侧部的高度为h（具体地，在本实施例中，所述膜层6的侧部的高度为所述黑矩阵61的高度），所述内层挡墙2最低处（在本实施例中，即为所述内层挡墙2的低洼处）的高度为d，其中，h-d≤4μm时，可有效避免配向液溢出，让部分配向液被容置于所述内层挡墙2和所述外层挡墙3之间的区域，从而减缓配向液外扩的趋势。
以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
