具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的 本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
图1a为一种液晶显示面板剖视图，图1b为图1a所示显示面板沿AB方向的俯视图，如图1a和1b所示，液晶显示面板包括第一基板01、第二基板02以及位于两个显示基板之间的液晶层013。液晶层013位于液晶显示面板的显示区，且显示区还包括隔垫物014，用于维持显示面板盒厚的均匀性。例如，隔垫物014可以为感光性间隔柱，即利用感光性组合物的光刻法形成位置精确度高的隔垫物，包含树脂、聚合性化合物、光聚合引发剂等。在液晶显示面板的周边区设置封框胶012以密封液晶层013。例如，封框胶012的组成包括树脂、光重合开始材、光重合停止材、硬化剂等化学物质，经过紫外固化以及热固化作用后起到相应的连接作用。封框胶012的另一个作用为对显示面板周边区起到支撑作用，因此需要添加一定高度的硅球等支撑物，例如，选用的硅球的尺寸为3-5μm。
在研究中，本申请的发明人发现：ADS(Advanced Super Dimension Switch，高超维场转换技术)，通过同一平面内狭缝电极边缘所产生的电场以及狭缝电极层与板状电极层间形成多维电场，使液晶盒内狭缝电极间、电极正上方的所有取向液晶分子都能够产生水平旋转，从而提高了液晶工作效率并增大了透光率。ADS液晶分子在暗态时水平排列，存在一定的相位延迟量Φ1，Φ1约为320～380nm。大尺寸的ADS液晶显示屏，例如32寸、49寸、65寸等尺寸的电视机产品在制作成模组后，当液晶分子处于暗态时会出现周边固定位置漏光现象，即对显示面板不施加信号的情况下，只点亮背光源会发现周边固定位置漏光，严重影响产品质量。
图2为液晶显示面板固化时面板产生弯曲示意图，图2为沿图1a中的Y方向以及在图1b示出的周边区沿CD方向所截的截面示意图，如图2所示， 在第一基板01与第二基板02对盒完成前，对周边区进行封框胶012的涂布，且封框胶012中包含硅球0121等支撑物。由于在对盒及涂布封框胶过程中显示面板需要支撑台015的支撑，而支撑台015会对显示面板产生不均一的支撑并导致显示面板发生弯曲或形变，在封框胶012固化后形变保留。由于封框胶012的粘性较大，弹性较小，例如弹性模量为15GPa，因此支撑台015对显示面板周边的不均一支撑导致封框胶012形变量大且难以恢复，在封框胶012固化后，显示面板周边的形变被保留，此时第一基板01与第二基板02产生一定的相位延迟量Φ2，例如，相位延迟量Φ2约为1～10nm。两个显示基板产生的相位延迟量Φ2与液晶分子产生的相位延迟量Φ1的共同作用导致周边区固定位置产生了暗态漏光现象。而显示区域由于没有封框胶的固定作用，位于显示区域的上下显示基板不会产生相位延迟量，因此不会产生暗态漏光的不良现象。
另一方面，对液晶显示面板的周边区与显示区分别进行按压会发现：液晶显示面板的周边区在按压过程中产生亮度及颜色变化较大的现象，而液晶显示面板的显示区在按压过程中亮度及颜色变化较小，即面内按压的敏感性相比周边区域较好。液晶显示面板在进行模组的组装时，边框与液晶显示器之间虽然有一定间隙的设计，但不排除边框变形或其他原因导致边框对液晶显示器周边产生挤压，因此液晶显示器周边极易产生漏光不良。
图3a与图3b分别示出了按压液晶显示面板周边区域与显示区域时第一基板与第二基板受到的应力作用示意图，如图3a所示，手指016按压显示面板周边区域时，由于封框胶012的束缚作用，第一基板01受到的应力010的方向与第二基板02受到的应力020的方向相反，因此液晶显示面板周边区域的上下基板产生了相位延迟，该相位延迟在叠加液晶分子产生的相位延迟量Φ1后，导致周边区域产生的漏光量较大。
如图3b所示，手指016按压显示面板的显示区域，即手指016按压显示面板的面内区域时，由于面内有隔垫物014的弹性支撑作用(例如，隔垫物014的弹性模量为2.2GPa)，在按压显示面板时，第一基板01与第二基板02为相对灵活状态，即第一基板01受到的应力010的方向与第二基板02受到的应力020的方向相同，因此面内区域产生的漏光量较小。例如，液晶分子的相位延迟量Φ1选用350nm时，由于不同颜色光的波长不同，其产生漏光量有所差异，周边区域红色和绿色的漏光量相比较大，叠加后显黄色；而面内区域，蓝色的漏光量相比较大，按压后显示漏光为蓝色。
本公开的实施例提供一种显示面板及其制作方法、显示装置，该显示面板具有显示区及围绕显示区的周边区，包括第一基板、与第一基板相对设置的第二基板以及密封部件。该密封部件设置在第一基板与第二基板之间并设置在周边区内，被配置为密封连接第一基板与第二基板，其中，密封部件包括第一封框胶和第一挡墙，第一挡墙在第二基板上的正投影与第一封框胶在第二基板上的正投影至少部分交叠，第一封框胶的材料的弹性模量大于第一挡墙的材料的弹性模量。该显示面板通过在密封部件中添加第一挡墙既可以增加密封部件的弹性以改善显示面板周边固定位置漏光以及按压漏光的敏感性，又可以对显示面板起到支撑作用以减薄封框胶的厚度，从而简化封框胶的生产工艺，使第一封框胶中不需要添加硅球、塑料球等支撑物。
下面结合附图对本公开实施例提供的一种显示面板及其制作方法、显示装置、基板进行说明。
实施例一
图4a为本实施例提供的一种液晶显示面板的剖视图，如图4a所示，该显示面板具有显示区10以及围绕显示区10的周边区11，周边区11即为非显示区域。该显示面板包括第一基板101、与第一基板101相对设置的第二基板102以及密封部件110。例如，第一基板101为彩膜基板，第二基板102为阵列基板，本实施例对此不作限制。密封部件110设置在第一基板101与第二基板102之间并设置在周边区11内，即密封部件110围绕显示区10以对第一基板101与第二基板102起到密封连接作用。密封部件110中包括第一封框胶111和第一挡墙112，第一挡墙112在第二基板102上的正投影与第一封框胶111在第二基板102上的正投影至少部分交叠。
例如，第一封框胶111的组成可以包括树脂、光重合开始材、光重合停止材、硬化剂等化学物质，经过紫外固化以及热固化作用后固化并起到相应的连接作用。例如，第一封框胶111的粘性较大，弹性较小，例如弹性模量为15GPa，本实施例不限于此。例如，对第一封框胶111施加一个整体的压强p，这个压强称为“体积应力”，第一封框胶的体积减少量(-dV)除以原来的体积V称为“体积应变”，体积应力除以体积应变就等于弹性模量:K＝P/(-dV/V)，其中，单位：兆帕(MPa)。
例如，第一挡墙112可以为含氟涂料树脂等，本实施例对此不作限制。例如，第一挡墙112的弹性模量为2.2GPa，本实施例不限于此。
需要说明的是，本实施例中的第一封框胶111的材料的弹性模量大于第一挡墙112的材料的弹性模量，例如，第一封框胶111的弹性模量为第一挡墙112的弹性模量的5-10倍，即第一挡墙112相比于第一封框胶111具有较好的弹性，因此，本实施例提供的显示面板通过在密封部件中添加第一挡墙既可以增加密封部件的弹性以改善显示面板周边固定位置漏光以及按压漏光的敏感性，又可以对显示面板起到支撑作用以减薄封框胶的厚度，从而简化封框胶的生产工艺，使第一封框胶中不需要添加硅球、塑料球等支撑物。
如图4a所示，例如，第一挡墙112设置在第一基板101上，且第一挡墙112为围绕显示区10的至少一圈沿周边区11连续的条状挡墙。本实施例不限于此，例如，还可以是第一挡墙112设置在第二基板102上。
例如，第一挡墙112在沿垂直于第一基板101的方向的高度为3.0-4.5μm，即第一挡墙112沿Y方向的高度为3.0-4.5μm，本实施例不限于此。
图4a示出的第一挡墙112为多个条状挡墙，例如，在如图4a所示剖面图中，条状第一挡墙112可以采用等间距或不等间距设计，例如，间距为100-200μm，本实施例对此不作限制。需要说明的是，图4a只是示例性示意图，为了更好地示意显示面板中的结构，并不是完全依据各条状挡墙的高度及间距的尺寸比例而画。
例如，条状第一挡墙112在图4a示出的剖视图内为梯形，且该梯形在靠近第一基板101一侧的边长大于靠近第二基板102一侧的边长，本实施例不限于此，例如，条状第一挡墙112的剖视图还可以为矩形等。
例如，条状第一挡墙112包括多圈挡墙时，还可以为最内一圈挡墙为围绕显示区连续的挡墙，即靠近液晶层的一圈挡墙为连续型挡墙，其他外圈挡墙由多个紧密排列的挡块或多个具有一定间隙的挡块组成，本实施例对此不作限制，只要多圈条状第一挡墙的至少一圈为连续型挡墙以起到密封效果即可。
例如，条状第一挡墙112可以由多个挡块形成，图4b为组成条状第一挡墙的挡块示意图，如图4b所示，条状第一挡墙112可以由多个圆柱状的挡块1121形成，本实施例不限于此，例如，条状第一挡墙112还可以由多个柱状挡块1121形成，该柱状挡块1121可以为长方体，或者具有如图4a示出的梯形剖视图的挡块(该挡块与挡块之间可以实现紧密贴合连接)，本实施例对此不作限制。需要说明的是，图4b所示的挡块1121为用于形成连续型条状挡墙的挡块，若形成不连续的条状挡墙，则可以采用多个圆台状的挡块等。
这里采用条状第一挡墙设计可以使两个显示基板处于相对灵活的状态，即条状第一挡墙设计具有较好的弹性可恢复性，可以改善周边区域固定位置漏光现象及按压漏光的敏感性。
例如，如图4a所示，第一封框胶111设置在第一挡墙112沿垂直于第一基板101的方向上远离第一基板101的一侧且与第一挡墙112连接。例如，第一封框胶111可以设置在第二基板102上，第一挡墙112通过第一封框胶111与第二基板102粘结以实现密封作用。本实施例不限于此，例如，第一封框胶111还可以设置在第一挡墙112上。
例如，第一挡墙112沿Y方向的高度大于第一封框胶111沿Y方向的高度，例如，第一封框胶111沿Y方向的高度为0.2-0.5μm，本实施例对此不作限制。需要说明的是，本实施例中第一挡墙112的高度与第一封框胶111的高度之和与显示面板的盒厚尺寸的设计相一致。
例如，多个条状第一挡墙112靠近第一封框胶111一侧的表面在第二基板102上的正投影落入第一封框胶111在第二基板102上的正投影内，即第一挡墙112与第一封框胶111的接触面积等于第一挡墙112靠近第一封框胶111一侧的表面的面积，本实施例不限于此，只要第一挡墙与第一封框胶连接，并且两者构成的密封部件对显示面板具有较好密封连接作用即可。本实施例中在密封部件中添加的第一挡墙起到了支撑显示面板的作用，因此第一封框胶相对于传统的封框胶可以减薄厚度，并且不添加硅球、塑料球等支撑物以简化生产工艺。
例如，图4c为图4a示出的沿AB方向的液晶显示面板的俯视图，如图4c所示，第一挡墙112为三圈围绕显示区10连续的条状挡墙，本实施例不限于此，还可以是两圈或更多圈，根据实际尺寸需要而定。
例如，如图4c所示，显示面板还包括液晶层103，液晶层103位于显示区10，并且，在显示区10设置多个隔垫物104，即在液晶层103之中设置多个隔垫物104以维持显示面板盒厚的均匀性。
例如，隔垫物104可以为感光性间隔柱，即利用感光性组合物的光刻法形成位置精确度高的隔垫物，隔垫物104包含树脂、聚合性化合物、光聚合引发剂等，本实施例不限于此。
需要说明的是，隔垫物104的材料与第一挡墙112的材料相同，即第一挡墙112与隔垫物104具有相同的弹性模量。例如，沿垂直于第一基板101的方 向，第一挡墙112的高度与隔垫物104的高度相同，即第一挡墙112沿Y方向的高度与隔垫物104沿Y方向的高度相同，例如，第一挡墙112与隔垫物104的高度均为3.0-4.5μm，本实施例包括但不限于此。例如，本实施例中将隔垫物104与第一挡墙112采用半色调掩膜(half tone mask)工艺在同一步骤形成以节省工艺。
例如，图5a为本实施例的另一示例提供的一种液晶显示面板的剖视图，图5b为图5a示出的沿AB方向的液晶显示面板的俯视图。如图5a和图5b所示，在第一基板101上设置第一挡墙112，第一挡墙112为一圈围绕显示区10的连续的挡墙，即第一挡墙112为一圈沿周边区11连续的块状挡墙。本实施例不限于此，例如，还可以在第二基板102上设置一圈围绕显示区10连续的块状第一挡墙112。
例如，图5a示出了第一挡墙112靠近第一封框胶111一侧的表面在第二基板102上的正投影落入第一封框胶111在第二基板102上的正投影内，本实施例不限于此，例如，还可以是第一封框胶111在第二基板102上的正投影落入第一挡墙112靠近第一封框胶111一侧的表面在第二基板102上的正投影内，即只要第一挡墙与第一封框胶连接，并且两者构成的密封部件对显示面板具有较好密封连接作用即可。
实施例二
与实施例一不同的是本实施例提供的密封部件还包括第二挡墙，且本实施例中的第一挡墙沿垂直于第一基板的方向的高度略小于实施例一中的第一挡墙的高度。
图6a为本实施例提供的一种液晶显示面板的剖视图，如图6a所示，密封部件110还包括第二挡墙213，沿垂直于第一基板101的方向上，第二挡墙213设置在第一封框胶111与第二基板102之间，且与第一封框胶111连接，即第二挡墙213设置在第一封框胶111远离第一挡墙112的一侧，以实现密封作用。例如，第二挡墙213可以设置在第二基板102上。
在一个示例中，如图6a所示，第一挡墙112为围绕显示区10的多圈连续的条状挡墙，第二挡墙213为围绕显示区10的一圈连续的块状挡墙。例如，第一封框胶111在第二基板102上的正投影落入第二挡墙213在第二基板102上的正投影内。例如，第二挡墙213沿X方向的宽度为1-2mm，第一封框胶111沿X方向的宽度为0.5-1.5mm，即第二挡墙213沿X方向的宽度略大于第 一封框胶111沿X方向的宽度，本实施例包括但不限于此。这里采用条状第一挡墙设计可以使两个显示基板处于相对灵活的状态，即条状第一挡墙设计具有较好的弹性可恢复性，可以改善显示面板周边区域固定位置漏光现象及按压漏光的敏感性。
本实施例不限于条状第一挡墙的设计，例如，图6b为本实施例中另一示例提供的一种液晶显示面板的剖视图，如图6b所示，第一挡墙112为围绕显示区10的一圈连续的块状挡墙，即第一挡墙112与第二挡墙213均为围绕显示区10的一圈连续的块状挡墙。
需要说明的是，本实施例中第一封框胶111的材料的弹性模量大于第二挡墙213的材料的弹性模量以增加密封部件110的弹性，从而可以改善显示面板固定位置漏光的现象以及按压漏光的敏感性。
例如，第二挡墙213的材料与第一挡墙112的材料相同，本实施对此不作限制。
例如，本实施例中的第一挡墙112沿Y方向的高度为2-3μm(略小于实施例一中第一挡墙112沿Y方向的高度)，第二挡墙213沿Y方向的高度为1-1.5μm，第一封框胶111沿Y方向的高度仍可选用0.2-0.5μm，即第一挡墙112的高度与第二挡墙213的高度均大于第一封框胶111的高度，本实施例对此不作限制。例如，本实施例中第一挡墙112沿Y方向的高度与第二挡墙213沿Y方向的高度之和大于第一封框胶111沿Y方向的高度。
需要说明的是，本实施例中第一挡墙112的高度、第一封框胶111的高度以及第二挡墙213的高度之和与显示面板的盒厚尺寸的设计相一致。由于在密封部件中添加的第一挡墙与第二挡墙起到了支撑显示面板的作用，因此第一封框胶相对于传统的封框胶可以减薄厚度，并且不添加硅球、塑料球等以简化生产工艺。
例如，沿垂直于第一基板101的方向，第一挡墙112与第二挡墙213的高度之和与隔垫物104的高度相同，即第一挡墙112与第二挡墙213沿Y方向的高度之和与隔垫物104沿Y方向的高度相同。例如，第一挡墙112与第二挡墙213的高度之和与隔垫物104的高度均为3.0-4.5μm，本实施例包括但不限于此。例如，第一挡墙112与隔垫物104可以通过采用半色调掩膜(half tone mask)工艺在同一步图案化工艺中完成以节省工艺。
实施例三
与实施例一不同的是本实施例提供的密封部件还包括第二封框胶，且本实施例中的第一挡墙沿垂直于第一基板的方向的高度略小于实施例一中的第一挡墙的高度。
图7a为本实施例提供的一种液晶显示面板的剖视图，如图7a所示，在沿垂直于第一基板101的方向上，第二封框胶314设置第一挡墙112与第一基板101之间，且与第一挡墙112连接，即第二封框胶314设置在第一挡墙112远离第一封框胶111的一侧，以实现密封作用。例如，第二封框胶314设置在第一基板101上。
例如，在一个示例中，如图7a所示，第一挡墙112为围绕显示区的多圈连续的条状挡墙。例如，第一挡墙112靠近第二封框胶314一侧的表面在第一基板101上的正投影落入第二封框胶314在第一基板101的正投影内，即第一挡墙112沿X方向的宽度小于第二封框胶314沿X方向的宽度，本实施例不限于此，只要第一挡墙112与第二封框胶314可以实现密封连接效果即可。这里采用条状第一挡墙设计可以使两个显示基板处于相对灵活的状态，即条状第一挡墙设计具有较好的弹性可恢复性，可以改善周边区域固定位置漏光现象及按压漏光的敏感性。
本实施例不限于条状第一挡墙的设计，例如，图7b为本实施例中另一示例提供的一种液晶显示面板的剖视图，如图7b所示，第一挡墙112为围绕显示区10的一圈连续的块状挡墙。
需要说明的是，本实施例中第二封框胶314的材料的弹性模量大于第一挡墙112的材料的弹性模量，从而可以改善显示面板固定位置漏光的现象以及按压漏光的敏感性。
例如，第二封框胶314的材料与第一封框胶111的材料相同，本实施对此不作限制。
例如，第二封框胶314沿Y方向的高度与第一封框胶111沿Y方向的高度相同，例如，第一封框胶111与第二封框胶314沿Y方向的高度可选用0.2-0.5μm，本实施对此不作限制。
例如，第一挡墙112沿垂直于第一基板101的方向的高度为3.0-4.0μm(略小于实施例一中第一挡墙112沿垂直于第一基板101的方向的高度)，本实施例包括但不限于此。本实施例中第一挡墙112的高度略小于隔垫物104的高度。
需要说明的是，本实施例中第一挡墙112的高度、第一封框胶111的高度 以及第二封框胶314的高度之和与显示面板的盒厚尺寸的设计相一致。由于密封部件中添加的第一挡墙起到了支撑显示面板的作用，因此第一封框胶与第二封框胶相对于传统的封框胶可以减薄厚度，并且不添加硅球、塑料球等以简化生产工艺。
例如，图7c为本实施例中另一示例提供的一种液晶显示面板的剖视图，如图7c所示，还可以在第一封框胶111与第二基板102之间设置如实施例二中的第二挡墙213，且第二挡墙213连接到第一封框胶111，本实施例对此不作限制。需要说明的是，这里第一挡墙112的高度、第一封框胶111的高度、第二挡墙213的高度以及第二封框胶314的高度之和与显示面板的盒厚尺寸的设计相一致。
实施例四
本实施例提供一种显示面板的制作方法，如图8所示，该显示面板的制作方法的具体步骤如下，包括：
S401：提供第一基板。
例如，第一基板为彩膜基板，本实施例对此不作限制，例如，第一基板还可以为阵列基板。
S402：在第一基板上形成密封部件，形成密封部件包括在第一基板上形成第一挡墙，在第一挡墙远离第一基板的一侧形成第一封框胶。
例如，第一封框胶经过紫外固化以及热固化作用后固化并起到相应的连接作用。例如，第一封框胶的粘性较大，弹性较小，例如弹性模量为15GPa，本实施例不限于此。
例如，第一挡墙可以为含氟涂料树脂等，本实施例对此不作限制。例如，第一挡墙的弹性模量为2.2GPa，本实施例不限于此。
需要说明的是，本实施例中的第一封框胶的材料的弹性模量大于第一挡墙的材料的弹性模量，例如，第一封框胶的弹性模量为第一挡墙的弹性模量的5-10倍，即第一挡墙相比于第一封框胶具有较好的弹性，因此，本实施例提供的显示面板的制作方法通过在密封部件中添加第一挡墙，既可以增加密封部件的弹性以改善显示面板周边固定位置漏光以及按压漏光的敏感性，又可以对显示面板起到支撑作用以减薄封框胶的厚度，从而简化封框胶的生产工艺，使第一封框胶中不需要添加硅球、塑料球等支撑物。
S403：提供第二基板。
例如，第二基板为阵列基板，本实施例对此不作限制，例如，第二基板还可以为彩膜基板。
S404：将第一基板形成有密封部件的一侧与第二基板对盒以形成显示面板。
例如，显示面板包括显示区及围绕显示区的周边区，周边区即为非显示区域。密封部件形成于周边区以密封连接第一基板与第二基板。
例如，在第一基板面向第二基板的一侧的显示区形成液晶层，并在真空条件下完成第一基板与第二基板的对盒。
例如，本实施例提供的显示面板的制作方法还包括在显示区形成多个隔垫物，且隔垫物与第一挡墙在同一步骤中形成，即隔垫物与第一挡墙采用相同的材料形成以节省工艺步骤。
图9a为本实施例中一个示例提供的形成密封部件的步骤，如图9a所示，具体步骤包括：
S411：在第一基板上形成第一挡墙。
例如，在第一基板周边区涂敷用于形成第一挡墙的材料，经紫外光固化后形成本实施例提供的第一挡墙。
例如，第一挡墙为围绕显示区的至少一圈连续的挡墙，例如，第一挡墙为围绕显示区的一圈连续的块状挡墙或者第一挡墙为围绕显示区的多圈连续的条状挡墙，本实施例对此不作限制。
例如，条状第一挡墙(如图4a所示剖面图)可以采用等间距或不等间距设计，例如，间距为100-200μm，本实施例对此不作限制。采用条状挡墙设计可以使显示基板处于相对灵活的状态，即条状挡墙设计具有较好的弹性可恢复性，可以改善显示面板周边区域固定位置漏光的现象及按压漏光的敏感性。
S412：在第一挡墙沿垂直于第一基板的方向上远离第一基板的一侧形成第一封框胶以连接第一挡墙与第二基板。
例如，第一封框胶涂敷在第二基板的周边区，第一挡墙通过第一封框胶与第二基板粘结以实现密封作用。例如，第一封框胶既可以形成在第二基板上，也可以形成在第一挡墙上以实现第一封框胶与第二基板的密封粘结，本实施例对此不作限制。
例如，在第一基板或第二基板的显示区滴注液晶，然后在第二基板的周边区或第一挡墙上面向第二基板的一侧涂敷用于形成第一封框胶的材料，并在真 空条件下完成第一基板与第二基板的对盒，用于形成第一封框胶的材料经过紫外光照固化以及加热固化，从而起到密封连接作用。本实施例通过在密封部件中添加第一挡墙既可以增加密封部件的弹性以改善显示面板周边固定位置漏光以及按压漏光的敏感性，又可以对显示面板起到支撑作用以减薄封框胶的厚度，从而简化封框胶的生产工艺，使第一封框胶中不需要添加硅球、塑料球等支撑物。
例如，第一挡墙在沿垂直于第一基板的方向的高度为3.0-4.5μm，第一封框胶沿垂直于第一基板的方向的高度为0.2-0.5μm，即第一挡墙的高度大于第一封框胶的高度，本实施例对此不作限制。
例如，第一挡墙沿垂直于第一基板的方向的高度与隔垫物沿垂直于第一基板的方向的高度相同，例如，第一挡墙与隔垫物的高度均为3.0-4.5μm，本实施例包括但不限于此。例如，第一挡墙与隔垫物可利用一步图案化工艺形成以节省工艺。
需要说明的是，本实施例中第一挡墙的高度与第一封框胶的高度之和与显示面板的盒厚尺寸的设计相一致。
图9b为本实施例中另一示例提供的形成密封部件的步骤，如图9b所示，具体步骤包括：
S421：在第一基板上形成第一挡墙。
例如，第一挡墙为围绕显示区的至少一圈连续的挡墙，例如，第一挡墙为围绕显示区的一圈连续的块状挡墙或者第一挡墙为围绕显示区的多圈连续的条状挡墙，本实施例对此不作限制。
S422：在第二基板上形成第二挡墙。
例如，在第二基板周边区涂敷用于形成第二挡墙的材料，经紫外光固化后形成本实施例提供的第二挡墙。
例如，第二挡墙为围绕显示区的一圈连续的块状挡墙。
S423：在第一挡墙或第二挡墙上形成第一封框胶以连接第一挡墙与第二挡墙。
例如，在第一基板或第二基板的显示区滴注液晶，在第一挡墙上或第二挡墙上涂敷第一封框胶，并在真空条件下完成第一基板与第二基板的对盒，第一封框胶经过紫外光照固化以及加热固化，从而起到密封连接作用。
例如，第二挡墙的材料与第一挡墙的材料相同，本实施对此不作限制。
需要说明的是，本实施例中第一封框胶的材料的弹性模量大于第二挡墙的材料的弹性模量以增加密封部件的弹性，从而可以改善显示面板固定位置漏光的现象以及按压漏光的敏感性。
例如，本实施例中的第一挡墙沿垂直于第一基板的方向的高度为2-3.0μm，第二挡墙沿垂直于第一基板的方向的高度为1-1.5μm，第一封框胶的高度仍可选用0.2-0.5μm，本实施例对此不作限制。
需要说明的是，本实施例中第一挡墙的高度、第一封框胶的高度以及第二挡墙的高度之和与显示面板的盒厚尺寸的设计相一致。由于密封部件中添加的第一挡墙与第二挡墙起到了支撑显示面板的作用，因此第一封框胶相对于传统的封框胶可以减薄厚度，并且不添加硅球、塑料球等以简化生产工艺。
例如，第一挡墙与第二挡墙沿垂直于第一基板的方向的高度之和与隔垫物沿垂直于第一基板的方向的高度相同，例如，第一挡墙与第二挡墙的高度之和与隔垫物的高度均为3.0-4.5μm，本实施例包括但不限于此。例如，第一挡墙与隔垫物可以利用采用半色调掩膜(half tone mask)工艺在同一步图案化工艺形成以节省工艺。
图9c为本实施例中另一示例提供的形成密封部件的步骤，如图9c所示，具体步骤包括：
S431：在第一基板上形成第二封框胶。
例如，在第一基板的周边区涂敷用于形成第二封框胶的材料，经过紫外光照固化以及加热固化后形成本实施例提供的第二封框胶。
S432：在第二封框胶上形成第一挡墙。
例如，在第二封框胶上涂敷用于形成第一挡墙的材料，经紫外光固化后形成本实施例提供的第一挡墙。
S433：在沿垂直于第一基板的方向上第一挡墙靠近第二基板的一侧形成第一封框胶以连接第一挡墙与第二基板。
例如，在第一基板或第二基板的显示区滴注液晶，在第二基板上或第一挡墙上形成第一封框胶，并在真空条件下完成第一基板与第二基板的对盒，第一封框胶经过紫外光照固化以及加热固化，从而起到密封连接作用。
例如，形成的第一挡墙靠近第二封框胶一侧的表面在第一基板上的正投影落入第二封框胶在第一基板上的正投影内，本实施例不限于此。
需要说明的是，本实施例中第二封框胶的材料的弹性模量大于第一挡墙的 材料的弹性模量，从而可以改善显示面板固定位置漏光的现象以及按压漏光的敏感性。
例如，第二封框胶的材料与第一封框胶的材料相同，本实施对此不作限制。
例如，第二封框胶沿垂直于第一基板的方向的高度与第一封框胶沿垂直于第一基板的方向的高度相同，例如，第一封框胶与第二封框胶沿垂直于第一基板的方向的高度可选用0.2-0.5μm，本实施对此不作限制。
例如，第一挡墙沿垂直于第一基板的方向的高度为3.0-4.0μm，本实施例包括但不限于此。本实施例中第一挡墙的高度略小于隔垫物的高度。
需要说明的是，本实施例中第一挡墙的高度、第一封框胶的高度以及第二封框胶的高度之和与显示面板的盒厚尺寸的设计相一致。本实施例中在密封部件中添加的第一挡墙起到了支撑显示面板的作用，因此第一封框胶与第二封框胶相对于传统的封框胶可以减薄厚度，并且不添加硅球、塑料球等以简化生产工艺。
例如，本示例中还可以在第一封框胶与第二基板之间形成如步骤S422中所示的第二挡墙，且第二挡墙连接到第一封框胶，本实施例对此不作限制。需要说明的是，这里第一挡墙的高度、第一封框胶的高度、第二挡墙的高度以及第二封框胶的高度之和与显示面板的盒厚尺寸的设计相一致。
